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.

2024-09-03Merge patch series "Make LMB memory map global and persistent"Tom Rini
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. [1] - https://lore.kernel.org/u-boot/20240704073544.670249-1-sughosh.ganu@linaro.org/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).

2024-09-03stm32mp: compute ram_top based on the optee base addressSughosh Ganu
The value of ram_top address currently gets computed in an indirect manner. The boot_fdt_add_mem_rsv_regions() function gets called first to reserve the memory region occupied by OP-TEE in the LMB memory map. This is followed by a call to the lmb_alloc() API, which returns an address which is below the OP-TEE base address. This address is the value of ram_top returned by the board_get_usable_ram_top() function. This has now changed, as the LMB memory map, which is no longer local, gets set up after relocation. Get the OP-TEE base address by reading the device tree, and set the ram_top from this value. Signed-off-by: Sughosh Ganu <sughosh.ganu@linaro.org>

2024-09-03sandbox: iommu: remove lmb allocation in the driverSughosh Ganu
The sandbox iommu driver uses the LMB module to allocate a particular range of memory for the device virtual address(DVA). This used to work earlier since the LMB memory map was caller specific and not global. But with the change to make the LMB allocations global and persistent, adding this memory range has other side effects. On the other hand, the sandbox iommu test expects to see this particular value of the DVA. Use the DVA address directly, instead of mapping it in the LMB memory map, and then have it allocated.

The current location of this buffer overlaps with the memory region reserved for the U-Boot image, which is at the top of the usable memory. This worked earlier as the LMB memory map was not global but caller specific, but fails now because of the overlap. Move the TCG event log buffer to the start of the ram memory region instead.

2024-09-03lmb: allow for resizing lmb regionsSughosh Ganu
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.
