At default, u-boot reserves the memory from SP - 4KB to DRAM end for lmb in arch_lmb_reserve. So lmb won't allocate any memory from it. But we found the 4K gap for SP is not enough now, because some FDT updating operations are added in our u-boot before jumping to kernel, which needs larger stack. This causes the lmb allocated memory is overwritten by stack. Fix the issue by implementing the board_lmb_reserve to reserve from SP - 16KB to memory end for lmb. Signed-off-by: Ye Li ye.li@nxp.com
Applied to u-boot-imx, master, thanks !
