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
bit 2:0 PARTITION_ACCESS
0x0: No access to boot partition (default)
0x1: Boot Area partition 1
0x2: Boot Area partition 2
0x3: Replay Protected Memory Block (RPMB)
0x4: Access to General Purpose partition 1
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:
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 which is also the value used to specify the
hardware partition of 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.
This represents no code changes.

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.
[1] - https://lore.kernel.org/u-boot/[email protected]/T/#t
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).

All of the current definitions of arch_lmb_reserve() are doing the
same thing -- reserve the region of memory occupied by U-Boot,
starting from the current stack address to the ram_top. Introduce a
function lmb_reserve_uboot_region() which does this, and do away with
the arch_lmb_reserve() function.
Instead of using the current value of stack pointer for starting the
reserved region, have a fixed value, considering the stack size config
value.

Allow for resizing of LMB regions if the region attributes match. The
current code returns a failure status on detecting an overlapping
address. This worked up until now since the LMB calls were not
persistent and global -- the LMB memory map was specific and private
to a given caller of the LMB API's.
With the change in the LMB code to make the LMB reservations
persistent, there needs to be a check on whether the memory region can
be resized, and then do it if so. To distinguish between memory that
cannot be resized, add a new flag, LMB_NOOVERWRITE. Reserving a region
of memory with this attribute would indicate that the region cannot be
resized.

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.

Fix signed vs unsigned compare in read check in _spl_load()
Issue: when info->read() returns a negative value because of an error,
the comparison of 'read' (signed) with 'sizeof(*header)'
(unsigned silently converts the negative value into a very
large unsigned value and the check on the error condition
always return false, i.e. the error is not detected
Symptoms: if spl_load_image_fat() is unable to find the file 'uImage',
the SPL phase of the boot process just hangs after displaying
the following line:
Trying to boot from MMC1
Fix: cast 'sizeof(*header)' to int so the compare is now between
signed types

The sandbox pinmux driver is used in the non-test devicetree as well as

pre-relocation to avoid ENODEV errors. Then, convert the pin groups and
functions to the new style, adding onewire group as well.

- drop unnecessary resetting of the console in tests
- drop unnecessary blank line before MMC output
- update the docs a little
- fix buildman test failure on newer Pythons
- a few other minor things
