86xx: Rename ccsr_ddr's sdram_mode_1, sdram_cfg_1 fields

2009-07-22T14:43:47+00:00

Rename sdram_mode_1 to sdram_mode and sdram_cfg_1 to sdram_cfg to match
the 86xx user's manual and other Freescale architectures

8xxx: Break out DMA code to a common file

2009-07-02T04:01:51+00:00

DMA support is now enabled via the CONFIG_FSL_DMA define instead of the
previous CONFIG_DDR_ECC

86xx: Add CPU_TYPE_ENTRY support

2009-06-30T13:24:22+00:00

Unify with 83xx and 85xx and use CPU_TYPE_ENTRY.  We are going to use
this to convey the # of cores and DDR width in the near future so its
good to keep in sync.

fsl/85xx, 86xx: Sync up DMA code

2009-06-12T22:17:58+00:00

The following changes were made to sync up the DMA code between the 85xx
and 86xx architectures which will make it easier to break out common
8xxx DMA code:

85xx:
- Don't set STRANSINT and SPCIORDER fields in SATR register.  These bits
  only have an affect when the SBPATMU bit is set.
- Write 0xffffffff instead of 0xfffffff to clear errors in the DMA
  status register.  We may as well clear all 32 bits of the register...

86xx:
- Add CONFIG_SYS_MPC86xx_DMA_ADDR define to address DMA registers
- Add clearing of errors in the DMA status register when initializing
  the controller
- Clear the channel start bit in the DMA mode register after a transfer

fsl: Create common fsl_dma.h for 85xx and 86xx cpus

2009-06-12T22:17:45+00:00

Break out DMA structures for the Freescale MPC85xx and MPC86xx cpus to
reduce a large amount of code duplication

Replace attribute references with attribute__

2009-04-27T23:01:39+00:00

__attribute__ follows gcc's documented syntax and is generally more
common than __attribute.  This change is only asthetic and should not
affect functionality.

86xx: Cleanup MP support

2009-04-01T20:29:44+00:00

* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx
* Introduce determine_mp_bootpg() helper.  We'll need this to address a
  bug introduced in v2009.03 with 86xx MP booting.  We have to make sure
  to reserve the region of memory used for the MP bootpg() so other
  u-boot code doesn't use it.
* Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to
  allow cmd_mp.c to build and work. In the future we should look at
  implementing all these functions. This could be common w/85xx if we
  use spin tables on 86xx.

86xx: Update CPU info output on bootup

2009-02-17T00:05:57+00:00

- Update style of 86xx CPU information on boot to more closely
  match 85xx boards
- Fix detection of 8641/8641D
- Use strmhz() to display frequencies
- Display L1 information
- Display L2 cache size
- Fixed CPU/SVR version output

86xx: Reset update

2009-02-17T00:05:56+00:00

Update the 86xx reset sequence to try executing a board-specific reset
function.  If the board-specific reset is not implemented or does not
succeed, then assert #HRESET_REQ.  Using #HRESET_REQ is a more standard
reset procedure than the previous method and allows all board
peripherals to be reset if needed.
