common: memsize: add RAM size probe based on alias detection

2026-04-21T23:49:39Z

Add probe_ram_size_by_alias() to detect RAM size by checking whether a write to one address aliases to another address. Compared to get_ram_size(), this function allows the caller to: - limit probing to a small set of required accesses - avoid touching reserved or already used memory regions - handle non-linear alias patterns On the iMX95 SoC, when used with LPDDR5, accesses beyond the end of an 8GB DDR configuration do not alias to the expected linear wrap-around addresses. Instead, the aliased addresses appear to follow a pattern related to the DDRC bank and bank-group addresses mapping. Experimentally, the observed pattern is: Write Read y00000000 -> x0001c000 y00004000 -> x00018000 y00008000 -> x00014000 y0000c000 -> x00010000 y00010000 -> x0000c000 y00014000 -> x00008000 y00018000 -> x00004000 y0001c000 -> x00000000 This helper makes it possible to probe RAM size by explicitly specifying the probed address and the expected alias address for each size check.

efi: Rename CONFIG_EFI to CONFIG_EFI_CLIENT

2025-07-26T05:34:28Z

The generic name 'EFI' would be more useful for common EFI features. At present it just refers to the EFI app and stub, which is confusing. Rename it to EFI_CLIENT Signed-off-by: Simon Glass

Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"

2024-05-20T19:35:03Z

As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

init.h: Add "struct cmd_tbl"

In order to avoid needing to add to this file, add "struct cmd_tbl" before the prototype for do_bdinfo(). Signed-off-by: Tom Rini

arm: init: export prev_bl_fdt_addr

2024-03-01T14:44:35Z

When booting U-Boot on board with a locked down first-stage bootloader, we emulate the Linux boot header. By passing the U-Boot FDT through this first-stage bootloader and retrieving it afterwards we can pre-populate the memory nodes and other info like the KASLR address. Add a function to export the FDT addr so that boards can use it over the built-in FDT. Don't check is_addr_accessible() here because we might not yet have a valid mem_map if it's going to be populated from the FDT, let the board do their own validation instead.

common: add prototype & rename populate_serial_number()

2023-10-23T14:07:06Z

Rename populate_serial_number() to a more descriptive serial_read_from_eeprom() and provide the missing function prototype. This is useful for boards that wish to read their serial number from EEPROM at init. Signed-off-by: Artur Rojek Reviewed-by: Simon Glass

event: Use an event to replace last_stage_init()

2023-08-31T17:16:55Z

Add a new event which handles this function. Convert existing use of the function to use the new event instead. Make sure that EVENT is enabled by affected boards, by selecting it from the LAST_STAGE_INIT option. For x86, enable it by default since all boards need it. For controlcenterdc, inline the get_tpm() function and make sure the event is not built in SPL. Signed-off-by: Simon Glass

freescale: Drop call to init_func_vid() in the init sequence

Use the misc_init_f event instead, which is designed for this purpose. All boards with CONFIG_VID already enable CONFIG_EVENT. Signed-off-by: Simon Glass
