powerpc/5200: fix lite5200 ethernet phy address

2010-06-15T20:47:04+00:00

According to my schematics, on Lite5200 board ethernet phy uses address
0 (all ADDR lines are pulled down). With this change I can talk to
onboard phy (LXT971) and correctly use autonegotiation.

powerpc/5200: fix oops during going to standby

2010-06-15T20:47:04+00:00

When going to standby mode mpc code maps the whole soc5200 node
to access warious MBAR registers. However as of_iomap uses 'reg'
property of device node, only small part of MBAR is getting mapped.
Thus pm code gets oops when trying to access high parts of MBAR.
As a way to overcome this, make mpc52xx_pm_prepare() explicitly
map whole MBAR (0xc0000).

powerpc/5200: add lite5200 onboard I2C eeprom and flash

2010-06-15T06:04:31+00:00

Add dts descriptions for onboard 256 byte I2C eeprom (pcf8582C-2)
and 16MB NOR flash (am29lv652d).

powerpc: Fix mpic_resume on early G5 macs

2010-06-15T05:02:37+00:00

mpic_resume() on G5 macs blindly dereferences mpic->fixups, but
it may legitimately be NULL (as on PowerMac7,2).  Add an explicit
check.

This fixes suspend-to-disk with one processor (maxcpus=1) for me.

powerpc: rtas_flash needs to use rtas_data_buf

2010-06-15T05:02:37+00:00

When trying to flash a machine via the update_flash command, Anton received the
following error:

    Restarting system.
    FLASH: kernel bug...flash list header addr above 4GB

The code in question has a comment that the flash list should be in
the kernel data and therefore under 4GB:

        /* NOTE: the "first" block list is a global var with no data
         * blocks in the kernel data segment.  We do this because
         * we want to ensure this block_list addr is under 4GB.
         */

Unfortunately the Kconfig option is marked tristate which means the variable
may not be in the kernel data and could be above 4GB.

Instead of relying on the data segment being below 4GB, use the static
data buffer allocated by the kernel for use by rtas.  Since we don't
use the header struct directly anymore, convert it to a simple pointer.

powerpc: Unconditionally enabled irq stacks

2010-06-15T05:02:37+00:00

Irq stacks provide an essential protection from stack overflows through
external interrupts, at the cost of two additionals stacks per CPU.

Enable them unconditionally to simplify the kernel build and prevent
people from accidentally disabling them.

powerpc/kexec: Wait for online/possible CPUs only.

2010-06-15T05:02:33+00:00

kexec_perpare_cpus_wait() iterates i through NR_CPUS to check
paca[i].kexec_state of each to make sure they have quiesced.
However now we have dynamic PACA allocation, paca[NR_CPUS] is not necessarily
valid and we overrun the array;  spurious "cpu is not possible, ignoring"
errors result.  This patch iterates for_each_online_cpu so stays
within the bounds of paca[] -- and every CPU is now 'possible'.

powerpc/boot: Remove addRamdisk.c since it is now unused

2010-06-15T05:02:32+00:00

It was used in the dim distant past for adding initrds to images
for legacy iSeries, but it's not even used for that now that we
have initramfs.  So remove it.
