ppc4xx: Fix incorrect MODTx setup for some DIMM configurations

2008-07-18T13:57:23+00:00

This patch fixes a problem with incorrect MODTx (On Die Termination)
setup for a configuration with multiple DIMM's and multiple ranks.
Without this change Katmai was unable to boot Linux with DDR2 frequency
>= 533MHz and mem>=3GB. With this patch Katmai successfully boots Linux
with DDR2 frequency = 640MHz and mem=4GB.

ppc4xx: Remove redundant ft_board_setup() functions from some 4xx boards

2008-07-13T13:04:11+00:00

This patch removes some ft_board_setup() functions from some 4xx boards.
This can be done since we now have a default weak implementation for this
in cpu/ppc4xx/fdt.c. Only board in need for a different/custom
implementation like canyonlands need their own version.

ppc4xx: Fix include sequence in 4xx_pcie.c

2008-07-11T13:07:23+00:00

This patch now moves common.h to the top of the inlcude list. This
is needed for boards with CONFIG_PHYS_64BIT set (e.g. katmai), so that
the phys_size_t/phys_addr_t are defined to the correct size in this
driver.

ppc4xx: Fix printf format warnings now visible with the updated format check

2008-07-10T07:58:06+00:00

This patch fixes ppc4xx related printf format warning. Those warnings are
now visible since patch dc4b0b38d4aadf08826f6c31270f1eecd27964fd
[Fix printf errors.] by Andrew Klossner has been applied. Thanks, this is
really helpful.

ppc4xx: Enable support for > 2GB SDRAM on AMCC Katmai

2008-07-10T07:14:01+00:00

Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM.
To support such configurations, we "only" map the first 2GB via the TLB's. We
need some free virtual address space for the remaining peripherals like, SoC
devices, FLASH etc.

Note that ECC is currently not supported on configurations with more than 2GB
SDRAM. This is because we only map the first 2GB on such systems, and therefore
the ECC parity byte of the remaining area can't be written.

2008-07-01T15:03:19+00:00

This patch fixes a bug where the 460EX/GT PCIe UTLSET1 register was
configured incorrectly. Thanks to Olga Buchonina from AMCC for pointing
this out.

ppc4xx: Fix 460EX errata with CPU lockup upon high AHB traffic

2008-06-30T13:20:41+00:00

This patch implements a fix provided by AMCC so that the lockup upon
simultanious traffic on AHB USB OTG, USB 2.0 and SATA doesn't occur
anymore:

Set SDR0_AHB_CFG[A2P_INCR4] (bit 24) and clear SDR0_AHB_CFG[A2P_PROT2]
(bit 25) for a new 460EX errata regarding concurrent use of AHB USB OTG,
USB 2.0 host and SATA.

This errata is not officially available yet. I'll update the comment
to add the errata number later.
