ppc: Move cpu/$CPU to arch/ppc/cpu/$CPU

2010-04-13T07:13:16+00:00

Signed-off-by: Peter Tyser

Replace "#include " with "#include "

2010-04-13T07:13:04+00:00

The appropriate include/asm-$ARCH directory should already by symlinked
to include/asm so using the whole "asm-$ARCH" path is unnecessary.

This change should also allow us to move the include/asm-$ARCH
directories into their appropriate lib/$ARCH/ directories.

i2c: Move PPC4xx I2C driver into drivers/i2c directory

2010-04-06T06:10:41+00:00

This patch moves the PPC4xx specific I2C device driver into the I2C
drivers directory. All 4xx config headers are updated to include this
driver.

ppc4xx: Fix problem with I2C bus >= 1 initialization

2010-03-30T11:05:05+00:00

This patch fixes a problem introduced with patch eb5eb2b0
[ppc4xx: Cleanup PPC4xx I2C infrastructure]. We need to assign the I2C
base address to the "i2c" pointer inside of the controller loop.
Otherwise controller 0 is initialized multiple times instead of
initializing each I2C controller sequentially.

Tested on Katmai.

ppc4xx fix unstable 440EPx bootstrap options

2010-03-24T13:27:01+00:00

440EPx fixed bootstrap options A, B, D, and E sets PLL FWDVA to a value = 1.
This results in the PLLOUTB being greater than the CPU clock frequency
resulting unstable 440EPx operation resulting in various software hang
conditions.

This patch reprograms the FWDVA satisfying the requirement of setting FWDVB
to a value greater than 1 while using one of the four deafult bootstrap options.

ppc4xx: Fix compilation error on ML2 board

2010-02-03T08:17:00+00:00

Recently this compilation error occurs:

Configuring for ML2 board...
traps.c: In function 'MachineCheckException':
traps.c:159: error: 'debugger_exception_handler' undeclared (first use
	in this function)
traps.c:159: error: (Each undeclared identifier is reported only once
traps.c:159: error: for each function it appears in.)

This patch now fixes it by including kgdb.h

ppc: remove -ffixed-r14 gcc option.

2010-01-26T18:30:16+00:00

This is no loger needed, free up r14 for general usage.

ppc: Use r12 instead of r14 as GOT pointer.

2010-01-26T18:30:13+00:00

r14 is not supposed to be clobbered by functions. Switch
to r12 and call GET_GOT when needed. This will allow u-boot
to loose the -ffixed-r14 gcc option.

ppc: Loose GOT access in IRQ

2010-01-26T18:30:12+00:00

Using the GOT in IRQ handlers requires r14 to be -ffixed-r14.
Avoid this by relocatate transfer_to_handler too.
This will allow to free up r14 later on.

ppc4xx: Allow setting a single SPD EEPROM address for DDR2 DIMMs

2010-01-21T07:18:37+00:00

On platforms where SPD EEPROM and another EEPROM have adjacent
I2C addresses SPD_EEPROM_ADDRESS should be defined as a single
element array, otherwise DDR2 setup code would fail with the
following error:

ERROR: Unknown DIMM detected in slot 1

However, fixing SPD_EEPROM_ADDRESS would result in another
error:

ERROR: DIMM's DDR1 and DDR2 type can not be mixed.

This happens because initdram() routine does not explicitly
initialize dimm_populated array. This patch fixes the problem.
