* MIPS: correctly work with disabled CONFIG_MMUAntony Pavlov2020-06-081-1/+5
| | | | | | | | | | | | | | There are some issues with CONFIG_MMU=n in MIPS configuration (e.g. qemu-malta_defconfig): * "Cannot request SDRAM region for stack" error message on start; * empty kseg1_ram0 region in the iomem command output. The patch fixes the problems by forcing KSEG1 memory region usage for CONFIG_MMU=n MIPS configurations.
