powerpc/5121: shared DIU framebuffer support

2010-08-01T23:06:44+00:00

MPC5121 DIU configuration/setup as initialized by the boot
loader currently will get lost while booting Linux. As a
result displaying the boot splash is not possible through
the boot process.

To prevent this we reserve configured DIU frame buffer
address range while booting and preserve AOI descriptor
and gamma table so that DIU continues displaying through
the whole boot process. On first open from user space
DIU frame buffer driver releases the reserved frame
buffer area and continues to operate as usual.

powerpc/fsl_soc: isolate legacy fsl_spi support to mpc832x_rdb boards

2009-04-01T15:59:23+00:00

The advantages of this:
- Don't encourage legacy support;
- Less external symbols, less code to compile-in for !MPC832x_RDB
  platforms.

spi_mpc83xx: rework chip selects handling

2009-04-01T15:59:22+00:00

The main purpose of this patch is to pass 'struct spi_device' to the chip
select handling routines.  This is needed so that we could implement
full-fledged OpenFirmware support for this driver.

While at it, also:
- Replace two {de,activate}_cs routines by single cs_contol().
- Don't duplicate platform data callbacks in mpc83xx_spi struct.

powerpc: Implement get_brgfreq() and get_baudrate() stubs

This is needed to not bother with ugly #ifdefs in the drivers.

powerpc: remove support for bootmem-allocated memory for the DIU driver

2008-10-13T16:09:59+00:00

Early versions of the Freescale DIU framebuffer driver depended on a bootmem
allocation of memory for the video buffer.  The need for this feature was
removed in commit 6b51d51a, so now we can remove the platform-specific code
that allocated that memory.

powerpc/mpc83xx: Power Management support

2008-07-16T22:57:30+00:00

Basic PM support for 83xx.  Standby is implemented as sleep.
Suspend-to-RAM is implemented as "deep sleep" (with the processor
turned off) on 831x.

powerpc: Add DIU platform code for MPC8610HPCD

2008-04-28T15:58:40+00:00

Add platform code to support Freescale DIU.  The platform code includes
framebuffer memory allocation, pixel format, monitor port, etc.

[POWERPC] 85xx/86xx: refactor RSTCR reset code

2007-10-08T13:38:47+00:00

On the majority of 85xx & 86xx we have a register that's ability to
assert HRESET_REQ to reset the board.  We refactored that code so it
can be shared between both platforms into fsl_soc.c and removed all
the duplication in each platform directory.
