dts: Deduplicate dtbs target

2024-10-15T01:32:04Z

The dtbs: target is almost identical in all architecture Makefiles. All architecture Makefiles include scripts/Makefile.dts . Deduplicate the dtbs: target into scripts/Makefile.dts .

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.

xtensa: Implement phys virt conversion for PTP_MMU

2024-07-04T22:08:37Z

For PTP_MMU our physical address is not directly mapped into virtual address space, we need to access physical memory from those fixed map segments. Implement phys_to_virt and virt_to_phys hook to reflect this setting. Tested-by: Max Filippov Signed-off-by: Jiaxun Yang

xtensa: Correct define of _end symbol

So U-Boot is using _end symbol to detect location of devicetree appended at the end of the ROM. It needs to be calculated based on end of .data load address, as in our lds .current address is address in RAM. Tested-by: Max Filippov Signed-off-by: Jiaxun Yang
