Subject: [PATCH] MIPS: BCM47xx: Simplify handling SPROM revisions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
After the big SPROM cleanup moving code to the bcm47xx_sprom_fill_auto
we ended up with few tiny functions, two of them being identical. Let's
get rid of these [12]-liners.
This also stops extracting higher SPROM revisions as revision 1. Now we
have that function nicely handling revisions we don't need it.

function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
To support (extract) SPROM on Broadcom ARM devices we should separate
SPROM code and make it a separated module. We won't want to export
bcm47xx_fill_sprom symbol so we should support SoC SPROM in the standard
fallback function and then modify ssb to use it.

This drops another symbol dependency between setup.c and sprom.c which
will allow us to make SPROM code a separated module (and share it with
ARM).
