[U-Boot] [PATCH 0/2] Fix several bugs in qemu-mips configuration
I recently played around with the qemu-mips configuration, and encountered several issues. Saving the environment to flash overwrites the U-Boot code, and the malloc pool isn't big enough for initr_malloc_bootparams(). This patchset fixes these issues.

This fixes an issue with the saveenv command causing U-Boot to no longer work on the QEMU Mips pseudoboard. Because the offset of the environment was being determined by CONFIG_SYS_MONITOR_LEN, and this value was less than the actual size of U-Boot, saveenv was overwriting parts of the U-Boot code. Because CONFIG_SYS_MONITOR_LEN is no longer used on MIPS, this patch removes it and places the environment at the end of the pseudoboard's 4MB flash.

Before this patch, CONFIG_SYS_BOOTPARAMS_LEN was the same size as CONFIG_SYS_MALLOC_LEN. So, if malloc() had previously been called, and initr_malloc_bootparams() was called, it would fail with an out-of- memory error. This patch fixes this issue by expanding the malloc pool to 256KB.

could you also fix include/configs/qemu-mips64.h? Thanks.
