Otherwise Linux will use wrong memory size which causes a kernel panic. Define CONFIG_MEMSIZE_IN_BYTES in malta.h to avoid that. Signed-off-by: Gabor Juhos Cc: Daniel Schwierzeck Cc: Paul Burton --- Note: The patch depends on Paul's 'MIPS Malta board support' series. If we want to fix the problem before his patches will be merged, I will send a different patch. -Gabor For the record, the kernel panic looks like this: qemu-malta # setenv ipaddr 10.0.2.1 qemu-malta # setenv serverip 10.0.2.2 qemu-malta # setenv ethadd 00:11:22:33:44:55 qemu-malta # tftp 0xa1000000 openwrt-malta-be-uImage-gzip Using pcnet#0 device TFTP from server 10.0.2.2; our IP address is 10.0.2.1 Filename 'openwrt-malta-be-uImage-gzip'.
