env: Use getenv_yesno() more generally

2012-12-13T18:46:55Z

Move the getenv_yesno() to env_common.c and change most checks for 'y' or 'n' to use this helper. Signed-off-by: Joe Hershberger

mpc5200: Add SPL support

2012-12-05T16:30:51Z

This patch adds SPL booting support (NOR flash) for the MPC5200 platforms. Signed-off-by: Stefan Roese

powerpc: Extract EPAPR_MAGIC constants into processor.h

2012-12-05T16:27:02Z

By extracting these defines into a header, they can be re-used by other C sources as well. This will be done by the SPL framework OS boot support. Signed-off-by: Stefan Roese

powerpc/mpc85xx: Fix a bug introduced by CONFIG_PPC_SPINTABLE_COMPATIBLE

2012-11-28T00:28:08Z

powerpc/85xx: update the work-around for P4080 erratum SERDES-9

2012-11-28T00:28:07Z

The documented work-around for P4080 erratum SERDES-9 has been updated. It is now compatible with the work-around for erratum A-4580. This requires adding a few bitfield macros for the BnTTLCRy0 register. Signed-off-by: Timur Tabi Signed-off-by: Andy Fleming

powerpc/p4080ds: fix PCI-e x8 link training down failure

2012-11-28T00:28:07Z

Due to SerDes configuration error, if we set the PCI-e controller link width as x8 in RCW and add a narrower width(such as x4, x2 or x1) PCI-e device to PCI-e slot, it fails to train down to the PCI-e device's link width. According to p4080ds errata PCIe-A003, we reset the PCI-e controller link width to x4 in u-boot. Then it can train down to x2 or x1 width to make the PCI-e link between RC and EP.

powerpc/85xx: implement check for erratum A-004580 work-around

2012-11-28T00:28:07Z

The work-around for erratum A-004580 ("Internal tracking loop can falsely lock causing unrecoverable bit errors") is implemented via the PBI (pre-boot initialization code, typically attached to the RCW binary). This is because the work-around is easier to implement in PBI than in U-Boot itself. It is still useful, however, for the 'errata' command to tell us whether the work-around has been applied. For A-004580, we can do this by verifying that the values in the specific registers that the work-around says to update. This change requires access to the SerDes lane sub-structure in serdes_corenet_t, so we make it a named struct. Signed-off-by: Timur Tabi Signed-off-by: Andy Fleming

powerpc/mpc8xxx: take fdt_fixup_crypto_node() off the checkstack list

powerpc/mpc85xx: Temporary fix for spin table backward compatibility

2012-11-28T00:28:06Z

Once u-boot sets the spin table to cache-enabled memory, old kernel which uses cache-inhibit mapping without coherence will not work properly. We use this temporary fix until kernel has updated its spin table code. For now this fix is activated by default. To disable this fix for new kernel, set environmental variable "spin_table_compat=no". After kernel has updated spin table code, this default shall be changed.

powerpc/85xx: implement check for erratum A-004849 work-around

2012-11-28T00:28:06Z

The work-around for erratum A-004849 ("CoreNet fabric (CCF) can exhibit a deadlock under certain traffic patterns causing the system to hang") is implemented via the PBI (pre-boot initialization code, typically attached to the RCW binary). This is because the work-around is easier to implement in PBI than in U-Boot itself. It is still useful, however, for the 'errata' command to tell us whether the work-around has been applied.
