2023-08-15common: return type board_get_usable_ram_topHeinrich Schuchardt1-1/+1
board_get_usable_ram_top() returns a physical address that is stored in gd->ram_top. The return type of the function should be phys_addr_t like the current type of gd->ram_top. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

2023-07-17x86: Record the start and end of the tablesSimon Glass1-0/+4
The ACPI tables are special in that they are passed to EFI as a separate piece, independent of other tables. Also they can be spread over two areas of memory, e.g. with QEMU we end up with tables kept in high memory as well. Add new global_data fields to hold this information and update the bdinfo command to show the table areas. Move the rom_table_end variable into the loop that uses it.

2023-07-17x86: Improve the trampoline in 64-bit modeSimon Glass1-0/+11
At present this leaves the stack at the pre-relocation value. This is not ideal since we want to have U-Boot running entirely from the top of memory. In addition, the new global_data pointer is not actually used, since the global_data pointer itself is relocated, then the pre-relocation value is changed, so the effective value (after relocation) does not update. Adjust the implementation to follow the 32-bit code more closely, with a trampoline function which is passed the new stack and global_data pointer. This ensures that the correct values come through even when relocating. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

Correct this by using a different range for the pre-defined CPU numbers, above zero and out of the range of possible CPU values. For now it is safe to assume there are no more than 64K CPUs.
