sparc32: drop swapper_pg_dir

2012-07-26T23:46:15+00:00

We save one page of RAM dropping swapper_pg_dir.
It was only used for an assignment in init-mm.c and we
redid this later in srmmu.c anyway.

This is likely a left-over from the sun4c removal.

To avoid a dummy variable we use a simple #define swapper_pg_dir NULL

sparc32,leon: fix leon bootup

2012-05-29T19:47:36+00:00

head_32.S failed to set cputypval for leon, causing boot to fail.
The boot failed because we failed to recognize this was a LEON
cpu so we did not preoperly run-time patch the the kernel.
This resulted in an early crash.

sparc32: introduce sparc32_start_kernel called from head_32.S

2012-05-28T06:52:42+00:00

This gives us a C hook before we call start_kernel()

sparc32: implement proper LEON support in head_32 (after highmem)

2012-05-28T06:52:41+00:00

We use the compatibility property to determine the
sun models. For leon we use psr.impl and ignore the
result of the getprops call.

Include a hack to allow build as the support code
is not yet converted.

sparc32: implement proper LEON support in head_32 (before highmem)

2012-05-28T06:52:41+00:00

Use PSR to check if the CPU is LEON and jump to
LEON specific code in this case.

Added a few constants to psr.h to increase readability.

sparc32: string and whitespace cleanup in head_32.S

2012-05-28T06:52:40+00:00

A few strings have been adopted to show more relevant info.

Julian Calaby  pointed out one
that I would otherwise have missed.
