c1ab75c7d4 ppc4xx: Fix 440EPx bug in reconfigure_pll()
This patch fixes a bug in reconfigure_pll(), where the detection of
the current bootstrap option is wrong. The ICS bits where incorrectly
shifted. This bug was found on the lwmon5 board, which uses bootstrap
option H (I2C bootstrap EEPROM).

Additionally a bit of code was moved into the if statement, since its
only used after later on. No need to run this code all the time.

Also, a few empty lines are added to make the code better readable.

fe7cca715c ppc4xx: Enable booting with Option E on 460EX/EXr/GT
This patch enables booting with option E on the PPC460EX/EXr/GT.
When booting with Option E, the PLL is in bypass, CPR0_PLLC[ENG]=0.
The Software Boot Configuration Procedure is needed to engage the
PLL and perform a chip reset.

a47a12becf Move arch/ppc to arch/powerpc
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
