[U-Boot] [PATCH 1/2] board/qemu-mips: fix a typo in README
The 'Limitations & comments' section refers to the '-m mips' switch which is not valid. The '-m' switch can be used for setting the virtual RAM size:
$qemu-system-mips --help | grep '^-m ' -m megs set virtual RAM size to megs MB [default=128] $
The correct switch for specifying the machine type is '-M'. Fix the text to refer to that.

Limitations & comments ---------------------- -Supports the "-m mips" configuration of qemu: serial,NE2000,IDE. +Supports the "-M mips" configuration of qemu: serial,NE2000,IDE. Support is big endian only for now (or at least this is what I tested). Derived from au1x00 with a lot of things cut out.
Using the example command from the README file does not work as expected. qemu shows a text similar to the one below and it hangs.
$ qemu-system-mips -L . -nographic Could not open option rom 'pxe-pcnet.rom': No such file or directory qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin" qemu: terminating on signal 15 from pid 19726
This happens because qemu emulates a Malta board by default if the machine type is not defined explicitely on the command line.
For a working test, the '-M mips' switch is required:
$ qemu-system-mips -M mips -L . -nographic Could not open option rom 'vgabios.bin': No such file or directory
