2013-06-28bootm: Disable interrupts before loading OSSimon Glass
This restores the ordering of interrupt disable to what it what before commit 35fc84fa. It seems that on some archiectures (e.g. PowerPC) the OS is loaded into an interrupt region, which can cause problems if interrupts are still running.

2013-06-28cmd_bootm.c: Correct BOOTM_ERR_OVERLAP handlingTom Rini
With 35fc84fa1 [Refactor the bootm command to reduce code duplication] we stopped checking the return value of bootm_load_os (unintentionally!) and simply returned if we had a non-zero return value from the function. This broke the valid case of a legacy image file of a single kernel loaded into an overlapping memory area (the default way of booting nearly all TI platforms). The best way to fix this problem in the new code is to make bootm_load_os be the one to see if we have a problem with this, and if it's fatal return BOOTM_ERR_RESET and if it's not BOOTM_ERR_OVERLAP, so that we can avoid calling lmb_reserve() but continue with booting. We however still need to handle the other BOOTM_ERR values so re-work do_bootm_states so that we have an error handler at the bottom we can goto for problems from bootm_load_os, or problems from the other callers (as the code was before). Add a comment to do_bootm_states noting the existing restriction on negative return values. Signed-off-by: Tom Rini <trini@ti.com> --- Changes in v2: - Rework so that only bootm_load_os and boot_selected_os head down into the err case code, and other errors simply return back to the caller. Fixes 'spl export'.
2013-06-26Fix block device accesses beyond 2TiBSascha Silbe
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives. For some obscure reason, the current U-Boot code uses lbaint_t for the number of blocks to read (a rather optimistic estimation of how RAM sizes will evolve), but not for the starting address. Trying to access blocks beyond the 2TiB boundary will simply wrap around and read a block within the 0..2TiB range. We now use lbaint_t for block start addresses, too. This required changes to all block drivers as the signature of block_read(), block_write() and block_erase() in block_dev_desc_t changed. Signed-off-by: Sascha Silbe <t-uboot@infra-silbe.de>
2013-06-26cmd_bootm: Add command line arguments to Plan 9Steven Stallion
This patch introduces support for command line arguments to Plan 9. Plan 9 generally dedicates a small region of kernel memory (known as CONFADDR) for runtime configuration. A new environment variable named confaddr was introduced to indicate this location when copying arguments.

2013-06-26image: Add support for signing of FIT configurationsSimon Glass
While signing images is useful, it does not provide complete protection against several types of attack. For example, it it possible to create a FIT with the same signed images, but with the configuration changed such that a different one is selected (mix and match attack). It is also possible to substitute a signed image from an older FIT version into a newer FIT (roll-back attack). Add support for signing of FIT configurations using the libfdt's region support. Please see doc/uImage.FIT/signature.txt for more information. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26image: Add RSA support for image signingSimon Glass
RSA provides a public key encryption facility which is ideal for image signing and verification. Images are signed using a private key by mkimage. Then at run-time, the images are verified using a private key. This implementation uses openssl for the host part (mkimage). To avoid bringing large libraries into the U-Boot binary, the RSA public key is encoded using a simple numeric representation in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26image: Support signing of imagesSimon Glass

2013-06-26Add a 'fake' go command to the bootm commandSimon Glass
For tracing it is useful to run as much of U-Boot as possible so as to get a complete picture. Quite a bit of work happens in bootm, and we don't want to have to stop tracing before bootm starts. Add a way of doing a 'fake' boot of the OS - which does everything up to the point where U-Boot is about to jump to the OS image. This allows tracing to record right until the end. This requires arch support to work. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26Refactor the bootm command to reduce code duplicationSimon Glass
At present the bootm code is mostly duplicated for the plain 'bootm' command and its sub-command variant. This makes the code harder to maintain and means that changes must be made to several places. Introduce do_bootm_states() which performs selected portions of the bootm work, so that both plain 'bootm' and 'bootm <sub_command>' can use the same code. Additional duplication exists in bootz, so tidy that up as well. This is not intended to change behaviour, apart from minor fixes where the previously-duplicated code missed some chunks of code. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26Clarify bootm OS argumentsSimon Glass
At present the arguments to bootm are processed in a somewhat confusing way. Sub-functions must know how many arguments their calling functions have processed, and the OS boot function must also have this information. Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in the same way. Adjust the code so that arguments are removed from the list before calling a sub-function. This means that all functions can know that argv[0] is the first argument of which they need to take notice. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-06-24pxe: add support for per arch and SoC default pathsRob Herring
A pxelinux server setup for "default" menu is typically an x86 binary. This does not work well with a mixed architecture setup.

2013-06-24pxe: add support for ontimeout tokenRob Herring
ontimeout is similar to default, but is the selection on menu timeout. This is how cobbler sets a default. The label default is supposed to be the default selection when <enter> is pressed.

2013-06-24pxe: always display a menu when presentRob Herring
The prompt flag is for displaying a "boot:" prompt in pxelinux. This doesn't make sense for u-boot as we don't support the pxelinux command interface. So we should just ignore prompt statements and always show the menu if a menu is present. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2013-06-24pxe: try bootz if bootm fails to find a valid imageRob Herring

2013-06-24pxe: fix handling of different localboot valuesRob Herring
Add support for value of -1 For localboot. A value of -1 means return to u-boot prompt. The localboot value is often 0, so we need to distinguish the value from localboot being selected. A value of greater than or equal to 0 means attempt local boot command. If localboot is selected, we don't want to try other entries. Signed-off-by: Rob Herring <rob.herring@calxeda.com>

2013-06-13env_mmc: allow negative CONFIG_ENV_OFFSETStephen Warren
A negative value of CONFIG_ENV_OFFSET is treated as a backwards offset from the end of the eMMC device/partition, rather than a forwards offset from the start. This is useful when a single board may be stuffed with different eMMC devices, each of which has a different capacity, and you always want the environment to be stored at the very end of the device (or eMMC boot partition for example). One example of this case is NVIDIA's Ventana reference board. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

2013-06-12usb: ehci: add Faraday USB 2.0 EHCI supportKuo-Jung Su
This patch adds support to both Faraday FUSBH200 and FOTG210, the differences between Faraday EHCI and standard EHCI are listed bellow: 1. The PORTSC starts at 0x30 instead of 0x44. 2. The CONFIGFLAG(0x40) is not only un-implemented, and also has its address space removed. 3. Faraday EHCI is a TDI design, but it doesn't compatible with the general TDI implementation found at both U-Boot and Linux. 4. The ISOC descriptors differ from standard EHCI in several ways. But since U-boot doesn't support ISOC, we don't have to worry about that. Signed-off-by: Kuo-Jung Su <dantesu@faraday-tech.com> CC: Marek Vasut <marex@denx.de>

Some ARM compilers may emit code that makes unaligned accesses when faced with constructs such as: char mac[16] = "ethaddr"; Replace this with a strcpy() call instead to avoid this. strcpy() is used here, rather than replacing all usage of the mac variable with the string itself, since the loop itself sprintf()s to the variable each iteration, so strcpy() is doing basically the same thing.

2013-06-07generic_board: reduce the redundancy of gd_t struct membersMasahiro Yamada
This commit refactors common/board_f.c and common/board_r.c in order to delete the dest_addr and dest_addr_sp from gd_t struct. As mentioned as follows in include/asm-generic/global_data.h, /* TODO: is this the same as relocaddr, or something else? */ unsigned long dest_addr; /* Post-relocation address of U-Boot */ dest_addr is the same as relocaddr. Likewise, dest_addr_sp is the same as start_addr_sp. It seemed dest_addr/dest_addr_sp was used only as a scratch variable to calculate relocaddr/start_addr_sp, respectively. With a little refactoring, we can delete dest_addr and dest_addr_sp. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Simon Glass <sjg@chromium.org>
