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.

bootm: Adjust arguments of boot_os_fn

2023-12-21T21:07:52Z

Adjust boot_os_fn to use struct bootm_info instead of the separate argc, argv and image parameters. Update the handlers accordingly. Few of the functions make use of the arguments, so this improves code size slightly. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

microblaze: Remove common.h usage

2023-10-24T20:34:45Z

We can remove common.h from most cases of the code here, and only a few places need an additional header instead. Signed-off-by: Tom Rini Acked-by: Michal Simek

Correct SPL uses of LMB

2023-02-10T12:41:39Z

This converts 9 usages of this option to the non-SPL form, since there is no SPL_LMB defined in Kconfig Signed-off-by: Simon Glass

treewide: Drop bootm_headers_t typedef

2022-09-29T20:07:57Z

This is not needed and we should avoid typedefs. Use the struct instead. Signed-off-by: Simon Glass

zynqmp: Run board_get_usable_ram_top() only on main U-Boot

2022-07-26T06:23:54Z

With commit ce39ee28ec31 ("zynqmp: Do not place u-boot to reserved memory location"), the function board_get_usable_ram_top() is allocating MMU_SECTION_SIZE of about 2MB using lmb_alloc(). But we dont have this much memory in case of mini U-Boot. Keep these functions which use lmb under CONFIG_LMB so that they are compiled and used only when LMB is enabled.

microblaze: cache: introduce flush_cache_all()

2022-06-24T12:16:00Z

All flush_cache() calls in microblaze code are supposed to flush the entire instruction and data caches, so introduce flush_cache_all() helper to handle this. Also, provide implementations for flush_dcache_all() and invalidate_icache_all() so that icache and dcache u-boot commands can work.

microblaze: cache: introduce Kconfig options for icache/dcache sizes

2022-06-24T12:16:00Z

Replace XILINX_DCACHE_BYTE_SIZE macro with two Kconfig symbols for instruction and data caches sizes, respectively: CONFIG_XILINX_MICROBLAZE0_ICACHE_SIZE CONFIG_XILINX_MICROBLAZE0_DCACHE_SIZE Also, get rid of the hardcoded value in icache_disable().

microblaze: cache: improve dcache Kconfig options

2022-06-24T12:16:00Z

Replace CONFIG_DCACHE with a Kconfig option more limited in scope - XILINX_MICROBLAZE0_USE_WDC. It should be enabled if the processor supports the "wdc" (Write to Data Cache) instruction. It will be used to guard "wdc" invocations in microblaze cache code. Also, drop all ifdefs around flush_cache() calls and only keep one CONFIG_IS_ENABLED() guard within flush_cache() itself.
