treewide: Add a function to change page permissions

2025-03-14T11:37:54Z

For armv8 we are adding proper page permissions for the relocated U-Boot binary. Add a weak function that can be used across architectures to change the page permissions Tested-by: Neil Armstrong # on AML-S905X-CC Signed-off-by: Ilias Apalodimas

dts: Deduplicate dtbs target

treewide: drop redundant "type string" for SYS_SOC and friends

2024-09-10T19:14:59Z

The Kconfig symbols SYS_ARCH, SYS_CPU, SYS_SOC, SYS_VENDOR and SYS_BOARD are defined in arch/Kconfig as having type string, and most board files simply amend those definition with suitable default "foo" or default "foo" if BAR stanzas. But some also include a redundant repetition of the type. Homogenize the code base by removing those lines. Generated by find arch/*/ board -name Kconfig | xargs perl -i -g -pe 's/(config SYS_(ARCH|CPU|SOC|VENDOR|BOARD)\n)\s*string\n/\1/gs' with the trailing slash in arch/*/ ensuring that arch/Kconfig itself is not found. This does not change boards which add a prompt string, e.g. string "Board name" because I think those change the semantics of the symbol into being user-settable.

lmb: do away with arch_lmb_reserve()

2024-09-03T20:08:50Z

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.

lmb: make LMB memory map persistent and global

2024-09-03T20:08:50Z

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.
