treewide: Drop bootm_headers_t typedef

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.

arm: riscv: Remove additional ifdef from code guarded by CONFIG_IS_ENABLED

2022-07-26T06:23:54Z

CONFIG_OF_LIBFDT is used twice for guarding the same code. It is enough to do it once that's why remove additional ifdefs from arm and risc-v code.

Add a host Kconfig for OF_LIBFDT. With this we can use CONFIG_IS_ENABLED(OF_LIBFDT) directly in the tools build, so drop the unnecessary indirection. Signed-off-by: Simon Glass Reviewed-by: Alexandru Gagniuc

lmb: Always compile arch_lmb_reserve() into U-Boot on arm

2021-09-23T18:15:32Z

The arch_lmb_reserve() is called by lib/lmb.c lmb_reserve_common() even if CMD_BOOT{I,M,Z} is not enabled. However, the arm32/arm64 variant of arch_lmb_reserve() is only compiled in if CMD_BOOT{I,M,Z} is enabled. This currently does not trigger build error, because there is an empty weak implementation of arch_lmb_reserve(), however that is not the function that should be used on arm32/arm64. Fix this by moving the arch_lmb_reserve() implementation into common code and always compile it in.

Revert most of the series for adding vexpress_aemv8r support

2021-09-03T14:42:15Z

Per a request from Andre Przywara and agreed with by Peter Hoyes, the vexpress aemv8r support wasn't quite ready to be merged, but the discussion had moved off list. We should keep the first patch in the series for now, but revert the rest. This reverts the following commits: e0bd6f31ce41 doc: Add documentation for the Arm vexpress board configs 30e5a449e8c7 arm: Use armv8_switch_to_el1 env to switch to EL1 b53bbca63bf4 vexpress64: Add BASER_FVP vexpress board variant 2f5b7b74903f armv8: Add ARMv8 MPU configuration logic 37a757e227cc armv8: Ensure EL1&0 VMSA is enabled Signed-off-by: Tom Rini

arm: Use armv8_switch_to_el1 env to switch to EL1

2021-09-02T14:17:45Z

Use the environment variable armv8_switch_to_el1 to determine whether to switch to EL1 at runtime. This is an alternative to the CONFIG_ARMV8_SWITCH_TO_EL1 compile-time option. The environment variable will be ineffective if the ARMV8_MULTIENTRY config is used. This is required by the Armv8r64 architecture, which must be able to boot at S-EL1 for Linux but may need to boot at other ELs for other systems. Signed-off-by: Peter Hoyes

Revert "arm: bootm: Disable LMB reservation for command line and board info on arm64"

2021-08-08T15:59:01Z

This reverts commit 2359fa7a87848626bcbd3399e92c657595880cd7. While the goal is valid and there is surely unused memory in that area, we also have a lot of crucial things still located at the top-of-memory while running lmb_alloc_base. Such things are the page table (tlb_addr), relocated U-Boot and the active stack. Possibly more. So this patch was premature, we will need relocations of those things first if we want to use the range. Fixes booting on the IOT2050, but likely also on other boards. It got stuck on relocating the FDT - over the relocated U-Boot code. Signed-off-by: Jan Kiszka

arm: bootm: Disable LMB reservation for command line and board info on arm64

2021-07-09T16:15:41Z

On arm64, board info is not applicable and kernel command line patched into the DT, so the LMB reservation here makes no sense anymore. On legacy arm32, this might still be necessary on systems which do not use DT or use legacy ATAGS. Disable this LMB reservation on arm64. This also permits Linux DT to specify reserved memory node at address close to the end of DRAM bank, i.e. overlaping with U-Boot location. Since after boot, U-Boot will be no more, this is OK.

bootm: do not hang on failure

2021-04-12T21:17:11Z

On ARMv8 systems load mmc 0:1 $loadaddr vmlinuz-5.10.0-3-arm64 booti leads to a hanging system requiring to physically reset the system: FDT and ATAGS support not compiled in - hanging ### ERROR ### Please RESET the board ### For systems where physical access is difficult hanging is a poor choice. It is preferable to reset the system when U-Boot reaches a state that is not recoverable. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass
