MPC8260: fixup device tree by property instead of path

2009-05-15T20:03:09+00:00

cpu/mpc8260/cpu.c used to use do_fixup_by_path_u32() to update the
clock frequencies in the device tree, using a CPU path
"/cpus/OF_CPU", with OF_CPU beind defined in the board config file.

However, this does not work when one board config file (here:
MPC8260ADS.h) is intended to be used for several diffrent CPUs and
therefor contains a generic definition like "cpu@0", as the device
trees that will then be loaded will contain specific names like
"PowerPC,8272@0".

We switch to using do_fixup_by_prop_u32() instead, so we can search
for device_type="cpu", as it is done in other architectures, too.

Fix all linker script to handle all rodata sections

2009-03-20T21:39:12+00:00

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script.  Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.

However, '*(.rodata*)' by itself will result in sub-optimal section
ordering.  The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file.  This is easy to fix by using the
SORT_BY_ALIGNMENT command.

This patch has not be tested one most of the boards modified.  Some boards
have a linker script that looks something like this:

*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)

I change this to:

*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

cpu/: get mac address from environment

2009-03-20T21:39:11+00:00

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.

The cpus that get converted here:
	at91rm9200
	mpc512x
	mpc5xxx
	mpc8260
	mpc8xx
	ppc4xx

82xx serial, smc: add configurable SMC Rx buffer len

2009-02-09T23:54:42+00:00

This patch adds the configuration option CONFIG_SYS_SMC_RXBUFLEN.
With this option it is possible to allow the receive
buffer for the SMC on 82xx to be greater then 1. In case
CONFIG_SYS_SMC_RXBUFLEN == 1 this driver works as the
old version.

When defining CONFIG_SYS_SMC_RXBUFLEN also
CONFIG_SYS_MAXIDLE must be defined to setup the maximum
idle timeout for the SMC.

pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarity

2009-02-07T22:50:04+00:00

The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.

Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.
