2012-01-05Add bootstage accumulationSimon Glass
This adds a new type of boot timer, which records the time taken by an operation, rather than marking the instant when it occurred. This is useful to track the amount of time spent in a repeating activity during boot. To use this, call bootstage_start() at the start of the activity, then bootstage_accum() at the end, to add this segment of time to the total. You can call them (start first, then accum) as many times as you like.

2012-01-05usb: increase timeout on the control endpointVincent Palatin
Some USB keys are very slow at answering the initial GET_DESCRIPTOR or SET_ADDRESS request. I have encountered a couple of USB keys which take respectively 140ms and 230ms to send back their data packet on such a request, and thus fail with the current code. According to the USB2.0 standard 9.2.6.4, the device should answer the standard device requests (e.g. GET_DESCRIPTOR or SET_ADDRESS) in less than 500ms, so let's increase the control endpoint timeout to that value.

2011-12-20Security: Make sure not to overflow the in memory version of the GBBGabe Black
This is a revised version of this patch which fixes an ARM bug. This change plumbs the size of the GBB specified in the device tree to the functions that read it from the flash into memory, and adds checks to those functions to make sure they don't spill out of the in memory GBB. From a security standpoint this is a largely theoretical problem since the GBB is in the read only portion of flash and if that can be modified the machine is totally compromised, but it's possible somehow an attacker could force vboot to read the GBB from the wrong place. From a practical perspective it's not a bad idea to check this to avoid accidental memory corruption. BUG=chromium-os:24223 TEST=Built and booted on Lumpy. Built for Kaen.

2011-12-15Don't use bogus gbb address when booting up rewriteable firmware.Vadim Bendebury
https://gerrit.chromium.org/gerrit/11152 introduced a bug where the gbb pointer used during rewriteable firmware boot is bogus. The pointer is retrieved from the 'chromeos-config' section of the device tree, but on x86 platform this memory area is never initialized. The fix is to make sure that the proper gbb address in the CPU address space is used before gbb contents are accessed. What it boils down to is that when CONFIG_HARDWARE_MAPPED_SPI is set, gbb address should be determined before setup_gbb_and_cdata() is called. To accomplish that fdt_decode_twostop_fmap() is being modified to retrieve the flash base address among other things. Calling this function before setup_gbb_and_cdata() allows to assign the gbb pointer before it is used. `google-binary-block' is not yet being removed from the cromeos-config section of the device tree as this could break some tests.

2011-11-17UPSTREAM: net: tftpput: Add support for receiving ICMP packetsSimon Glass
ICMP packets can tell you when there is no server at the other end. It is useful for tftp to figure this out, so that a quick error can be displayed, rather than pointlessly retrying. This adds an ICMP packet handler to the net interface.

2011-11-04Introduce ability to use hardware SPI mapping for read accesses.Vadim Bendebury
On X86 systems the hardware maps the bootprom SPI flash chip into the top of memory address range. This could be used for accessing all information in the SPI flash. The vboot-reference code requires access to FMAP sections containing cryptographic information, and as of today, u-boot reads the whole sections, which are 64 KB in size, even though the actual areas accessed by vboot-reference are much smaller. A much faster way of accessing this information would be just passing around pointers to the appropriate memory areas. This would eliminate one copy, and also would make sure that only the areas actually accessed get fetched from SPI flash. This patch provides this ability trying to keep code changes to a minimum. New feature is enabled by defining CONFIG_HARDWARE_MAPPED_SPI. The firmware storage API for file reads changes when the new configuration option is set: a pointer to pointer to buffer is passed to the read_spi() function instead of a pointer to buffer. When the new feature is enabled the read_spi() function sets the pointer value to point to the requested data instead of copying the data into the buffer. A new data type is introduced (read_buf_type), which is set to be a (void *) if the new feature is not enabled, or (void **) otherwise. This type is used as the buffer pointer in the spi_read() function. Code allocating/freeing buffers used to keep data read from SPI flash is now conditionally compiled. Call sites for the spi_read() function are modified to adjust the buffer pointer parameter (pass the address of the parameter instead of the parameter, when the new feature is enabled). gbb field access functions can be aliased to gbb_init(), as they all in fact do the same - read a certain section of the gbb area. This change does not benefit the ARM implementations, and makes the code more complicated that it should be. Some u-boot rearchitecture along with vboot_reference API enhancements could address this. A tracking issue (http://code.google.com/p/chromium-os/issues/detail?id=22528) has been opened for that. BUG=chrome-os-partner:6585, chromium-os:22528 TEST=manual . build a new stumpy firmware image . boot the stumpy, observe it start up chromeos. . assess the boot timing using the cbmem.py utility (this modification shaves in excess of 100ms off the boot time). . disable the new feature, build a stumpy image, observe that is still boots chromeOs. . run emerge-terga2_kaen chromeos-u-boot to confirem that ARM version builds cleanly.
