powerpc/83xx: Fix PCI IO base address on MPC837xE-RDB boards

2009-07-30T04:18:41+00:00

U-Boot maps PCI IO at 0xe0300000, while current dts files specify
0xe2000000. This leads to the following oops with CONFIG_8139TOO_PIO=y.

8139too Fast Ethernet driver 0.9.28
Machine check in kernel mode.
Caused by (from SRR1=41000): Transfer error ack signal
Oops: Machine check, sig: 7 [#1]

This patch fixes the issue by specifying the correct PCI IO base
address.

powerpc/85xx: Don't scan for TBI PHY addresses on MPC8569E-MDS boards

2009-07-30T04:16:39+00:00

Sometimes (e.g. when there are no UEMs attached to a board)
fsl_pq_mdio_find_free() fails to find a spare address for a TBI PHY,
this is because get_phy_id() returns bogus 0x0000ffff values
(0xffffffff is expected), and therefore mdio bus probing fails with
the following message:

  fsl-pq_mdio: probe of e0082120.mdio failed with error -16

And obviously ethernet doesn't work after this.

This patch solves the problem by adding tbi-phy node into mdio node,
so that we won't scan for spare addresses, we'll just use a fixed one.

powerpc/4xx: Have Warp take advantage of GPIO LEDs default-state = keep

2009-07-06T12:56:01+00:00

The GPIO LEDS driver now has a default state of "keep".  Update the Warp DTS
and platform file to take advantage of this new state.  This removes the
hardcoding of the two LEDs on the Warp.

powerpc/amigaone: Limit ISA I/O range to 4k in the device tree

2009-06-26T04:37:23+00:00

The kernel reserves the I/O address space from 0x0 to 0xfff for legacy
ISA devices. Change the ranges property for the PCI2ISA bridge to match
the kernels behavior, even if the ranges property isn't used for now.

powerpc/85xx: Make eSDHC 1-bit only transfer mode default for MPC8569E-MDS

2009-06-23T13:10:00+00:00

For yet unknown reason 4-bit mode doesn't work on MPC8569E-MDS boards,
so make 1-bit mode default. When we resolve the issue, u-boot will
remove sdhci,1-bit-only property from the device tree, while SDHCI
will still work with older u-boots.
