Simon Glass <sjg@chromium.org> says:
When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the
above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.

This series is a reworked version of the previous seried:
misc: introduce STATUS LED activity function
This series port and expand the legacy concept of LED boot from
the legacy Status LED API to new LED API.
One thing that many device need is a way to communicate to the
user that the device is actually doing something.
This is especially useful for recovery steps where an
user (for example) insert an USB drive, keep a button pressed
and the device autorecover.
There is currently no way to signal the user externally that
the bootloader is processing/recoverying aside from setting
a LED on.
A solid LED on is not enough and won't actually signal any
kind of progress.
Solution is the good old blinking LED but uboot doesn't
suggest (and support) interrupts and almost all the LED
are usually GPIO LED that doesn't support HW blink.
Additional Kconfg are also introduced to set the LED boot and
activity. Those are referenced by label.
A documentation for old and these new LED API is created.

Added LMB API to prevent SF command from overwriting reserved
memory areas. The current SPI code does not use LMB APIs for
loading data into memory addresses. To resolve this, LMB APIs
were added to check the load address of an SF command and ensure it
does not overwrite reserved memory addresses. Similar checks are
used in TFTP, serial load, and boot code to prevent overwriting
reserved memory.

Modern eMMC v4+ devices have multiple hardware partitions per the JEDEC
specification described as:
Boot Area Partition 1
Boot Area Partition 2
RPMB Partition
General Purpose Partition 1
General Purpose Partition 2
General Purpose Partition 3
General Purpose Partition 4
User Data Area
These are referenced by fields in the PARTITION_CONFIG register
(Extended CSD Register 179) which is defined as:
bit 7: reserved
bit 6: BOOT_ACK
0x0: No boot acknowledge sent (default
0x1: Boot acknowledge sent during boot operation Bit
bit 5:3: BOOT_PARTITION_ENABLE
0x0: Device not boot enabled (default)
0x1: Boot Area partition 1 enabled for boot
0x2: Boot Area partition 2 enabled for boot
0x3-0x6: Reserved
0x7: User area enabled for boot

0x5: Access to General Purpose partition 2
0x6: Access to General Purpose partition 3
0x7: Access to General Purpose partition 4
Note that setting PARTITION_ACCESS to 0x0 results in selecting the User
Data Area partition.
You can see above that the two fields BOOT_PARTITION_ENABLE and
PARTITION_ACCESS do not use the same enumerated values.
U-Boot uses a set of macros to access fields of the PARTITION_CONFIG
register:
EXT_CSD_BOOT_ACK_ENABLE (1 << 6)
EXT_CSD_BOOT_PARTITION_ENABLE (1 << 3)
EXT_CSD_PARTITION_ACCESS_ENABLE (1 << 0)
EXT_CSD_PARTITION_ACCESS_DISABLE (0 << 0)
EXT_CSD_BOOT_ACK(x) (x << 6)
EXT_CSD_BOOT_PART_NUM(x) (x << 3)
EXT_CSD_PARTITION_ACCESS(x) (x << 0)
EXT_CSD_EXTRACT_BOOT_ACK(x) (((x) >> 6) & 0x1)
EXT_CSD_EXTRACT_BOOT_PART(x) (((x) >> 3) & 0x7)
EXT_CSD_EXTRACT_PARTITION_ACCESS(x) ((x) & 0x7)
There are various places in U-Boot where the BOOT_PARTITION_ENABLE field
is accessed via EXT_CSD_EXTRACT_PARTITION_ACCESS and converted to a
hardware partition consistent with the definition of the
PARTITION_ACCESS field used by the various mmc_switch incarnations.
To add some sanity to the distinction between BOOT_PARTITION_ENABLE
(used to specify the active device on power-cycle) and PARTITION_ACCESS
(used to switch between hardware partitions) create two enumerated types
and use them wherever struct mmc * part_config is used or the above
macros are used.
Additionally provide arrays of the field names and allow those to be
used in the 'mmc partconf' command and in board support files.
The first patch adds enumerated types and makes use of them which
represents no compiled code change.
The 2nd patch adds the array of names and uses them in the 'mmc
partconf' command.
The 3rd patch uses the array of hardware partition names in a board
support file to show what emmc hardware partition U-Boot is being loaded
from.

Sughosh Ganu <sughosh.ganu@linaro.org> says:
This is a follow-up from an earlier RFC series [1] for making the LMB
and EFI memory allocations work together. This is a non-rfc version
with only the LMB part of the patches, for making the LMB memory map
global and persistent.
This is part one of a set of patches which aim to have the LMB and EFI
memory allocations work together. This requires making the LMB memory
map global and persistent, instead of having local, caller specific
maps. This is being done keeping in mind the usage of LMB memory by
platforms where the same memory region can be used to load multiple
different images. What is not allowed is to overwrite memory that has
been allocated by the other module, currently the EFI memory
module. This is being achieved by introducing a new flag,
LMB_NOOVERWRITE, which represents memory which cannot be re-requested
once allocated.
The data structures (alloced lists) required for maintaining the LMB
map are initialised during board init. The LMB module is enabled by
default for the main U-Boot image, while it needs to be enabled for
SPL. This version also uses a stack implementation, as suggested by
Simon Glass to temporarily store the lmb structure instance which is
used during normal operation when running lmb tests. This does away
with the need to run the lmb tests separately.
The tests have been tweaked where needed because of these changes.
The second part of the patches, to be sent subsequently, would work on
having the EFI allocations work with the LMB API's.

Notes:
1) These patches are on next, as the alist patches have been
applied to that branch.
2) I have tested the boot on the ST DK2 board, but it would be good to
get a T-b/R-b from the ST maintainers.
3) It will be good to test these changes on a PowerPC platform
(ideally an 85xx, as I do not have one).

The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.
Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

Quite a few of the members of struct global_data are only used before
reloction, or have little meaning afterwards, yet they hang around in
struct global_data for the lifetime of U-Boot. This uses up precious

To help with this, start a new struct which exists only before
relocation. Move new_fdt into this new struct. Drop the display of it
