- patch dtb to add reserved-memory stanza for the phram device to use
(aarch64 does not accept memmap= command line option)
- patch phram driver to use memremap() instead of ioremap() as
ioremap can't be used for system ram on arm devices
New rules: everything under "config" that isn't actually configuration
(e.g. build products) will in future live in config.system. This is
the first step.
We now use MIPS_CMDLINE_DTB_EXTEND for all boot varieties
(tftpboot, flash boot, kexec) with the addition of
MIPS_BOOTLOADER_CMDLINE_REQUIRE_COOKIE - local patch -
so that the bootloader args are ignored unless they
contain the string "liminix"
* at the base address we were using, the filesystem was getting
corrupted presumably because the kernel unpacked into it
* leave a little more space between compressed kernel and
squashfs. this is probably ineffective but also harmless
