powerpc: Fix PCI in Holly device tree

2008-09-30T03:25:05+00:00

The PCI bridge on the Holly board is incorrectly represented in the
device tree.  The current device tree node for the PCI bridge sits
under the tsi-bridge node.  That's not obviously wrong, but the PCI
bridge translates some PCI spaces into CPU address ranges which were
not translated by the "ranges" property in tsi-bridge node.

We used to get away with this problem because the PCI bridge discovery
code was also buggy, assuming incorrectly that PCI host bridge nodes
were always directly under the root bus and treating the translated
addresses as raw CPU addresses, rather than parent bus addresses.
This has since been fixed, thus breaking Holly.

This could be fixed by adding extra translations to the tsi-bridge
node, but this patch instead moves the Holly PCI bridge out of the
tsi-bridge node to the root bus.  This makes the tsi-bridge node
represent only the built-in IO devices in the bridge, with a
more-or-less contiguous address range.  This is the same convention
used on Freescale SoC chips, where the "soc" node represents only the
IMMR region, and the PCI and other bus bridges are separate nodes
under the root bus.

powerpc: Holly board needs dtbImage target

2008-09-17T16:14:42+00:00

One of the changes in the bootwrapper makefile introduced the dtbImage
targets for boards that need a simple zImage with a DTB embedded in
them (595be948cce574ff2d5dde5d0426a636a4363c70, "[POWERPC]
bootwrapper: Build multiple cuImages").  When this was done, it broke
booting on the Holly board as the zImage.holly wrapper did not get the
DTB embedded properly.

This changes the target for the Holly board to a dtbImage so that the
wrapper includes the vmlinux, wrapper bits, and DTB.

powerpc: Fix interrupt values for DMA2 in MPC8610 HPCD device tree

2008-09-16T21:40:05+00:00

For Freescale 8xxx devices that use an MPIC, the interrupt numbers in
the device tree must be 16 greater than the values documented in the
reference manual.  In these chips, the MPIC is wired to use the first
16 numbers for external interrupts, but the documentation numbers
internal interrupts from 0.

In the MPC8610 HPCD device tree, the interrupt properties for the DMA
channels for DMA2 were not the adjusted values.  This fixes that.

powerpc: Fix rare boot build breakage

2008-09-08T05:55:35+00:00

A make -j20 powerpc kernel build broke a couple of months ago saying:
In file included from arch/powerpc/boot/gunzip_util.h:13,
                 from arch/powerpc/boot/prpmc2800.c:21:
arch/powerpc/boot/zlib.h:85: error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘*’ token
arch/powerpc/boot/zlib.h:630: warning: type defaults to ‘int’ in declaration of ‘Byte’
arch/powerpc/boot/zlib.h:630: error: expected ‘;’, ‘,’ or ‘)’ before ‘*’ token

It happened again yesterday: too rare for me to confirm the fix, but
it looks like the list of dependants on gunzip_util.h was incomplete.

powerpc/85xx: TQM8548: DTS file fixes and cleanup

2008-08-21T04:56:30+00:00

Due to the missing compatible property for the SOC, the MPC I2C buses are
not found any more. This patch fixes this issue. Furthermore it corrects
the name of the SOC node and adds the missing I2C node for the RTC.

powerpc: Fix whitespace merge in mpc8641 hpcn device tree

2008-08-21T04:26:02+00:00

When we coverted the .dts to v1 we lost a space between the irq
and its polarity/sense information.  This causes a bit of chaos
as the reset of the blob is off by one cell.

This was noticed by booting and getting errors w/ATA due to
lock of interrupts.
