Flush cache after the OS image is loaded into the memory.

2011-09-05T14:07:44+00:00

Since we are loading an executable image into memory we need flush it
out of the cache to possible maintain coherence on CPUs with split
instruction and data caches.  We do this for other executable image
loading command.

On PowerPC once we do this we no longer need to explicitly flush the
dcache on multi-core systems in the BOOTM_STATE_OS_PREP phase.  We now
treat the BOOTM_STATE_OS_PREP as a no-op to maintain backwards
compatibility with the bootm subcommand.

hwmon: do not init sensors on startup

2011-08-04T21:30:38+00:00

The U-Boot Design Principles[1] clearly say:

  Initialize devices only when they are needed within U-Boot, i.e. don't
  initialize the Ethernet interface(s) unless U-Boot performs a download
  over Ethernet; don't initialize any IDE or USB devices unless U-Boot
  actually tries to load files from these, etc. (and don't forget to
  shut down these devices after using them - otherwise nasty things may
  happen when you try to boot your OS).

So, do not initialize and read the sensors on startup.

powerpc/85xx: verify the device tree before booting Linux

2011-07-29T13:53:39+00:00

Introduce ft_verify_fdt(), a function that is called after the device tree
has been fixed up, that displays warning messages if there is a mismatch
between the physical addresses of some devices that U-Boot has configured
with what the device tree says the addresses are.

This is a particular problem when booting a 36-bit device tree from a
32-bit U-Boot (or vice versa), because the physical address of CCSR is
wrong in the device tree.  When the operating system boots, no messages are
displayed, so the user generally has no idea what's wrong.

powerpc/85xx: Fix setting of EPAPR_MAGIC value

2011-07-29T13:53:37+00:00

Had a typo in the ifdef for 85xx, should be CONFIG_MPC85xx for it to get
triggered.  Was pull in the non-BookE magic number.

powerpc: Fix device tree padding associated with ramdisk

2011-07-26T11:55:10+00:00

When booting with a ramdisk we bump the amount of memory reserved for
the device tree by FDT_RAMDISK_OVERHEAD.  However we did not increase
the actual size in the device tree blob to match.

Its possible on boundary cases that we dont have enough memory according
to the device tree blob and get errors like:

WARNING: could not set linux,initrd-end FDT_ERR_NOSPACE

We can easily fix this by setting the device tree size at the same time
we bump the amount of memory reserved for the device tree.

mpc832x: add support for the mpc8321 based suvd3 board

2011-04-29T22:44:29+00:00

- serial console on UART1
- Ethernet RMII over UCC4
- PHY SMSC LAN8700
- 64MB Flash
- 128 MB DDR2 RAM
- I2C
- bootcount

This board is similiar to the kmeter1 (8360) board,
so common config options are extracted into the
include/configs/km83xx-common.h file.
