2025-04-14common: board: make initcalls staticJerome Forissier
Change board_init_f(), board_init_f_r() and board_init_r() to make static calls instead of iterating over the init_sequence_f, init_sequence_f_r and init_sequence_r arrays, respectively. This makes the code a simpler (and even more so when initcall_run_list() is later removed) and it reduces the binary size as well. Tested with xilinx_zynqmp_kria_defconfig; bloat-o-meter results: - With LTO add/remove: 106/196 grow/shrink: 10/28 up/down: 31548/-33829 (-2281) Total: Before=1070471, After=1068190, chg -0.21% - Without LTO add/remove: 0/54 grow/shrink: 3/0 up/down: 2322/-2832 (-510) Total: Before=1121723, After=1121213, chg -0.05% Execution time does not change in a noticeable way.

2024-09-03lmb: do away with arch_lmb_reserve()Sughosh Ganu
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.

2024-09-03lmb: make LMB memory map persistent and globalSughosh Ganu
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.

Simon Glass <sjg@chromium.org> says: This series is the culmanation of the current line of refactoring series. It adjusts pxe to call the booting functionality directly rather than going through the command-line interface. With this is is possible to boot using the extlinux bootmeth without the command line enabled. It also updates fastboot to do a similar thing.

2019-09-02sh: Fix OF_SEPARATE supportMarek Vasut
If the OF_SEPARATE is enabled, the DT is appended past the _end symbol. The current code however clears BSS very early, which overwrites the DT blob with zeroes. Moreover, the early code relocates U-Boot into RAM to the correct location, but does not relocate the DT. This patch adds code to relocate the DT and avoids clearing BSS too early, thus addressing both problems with OF_SEPARATE on SH.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
