Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.
This was done with:
#!/bin/bash
mach_dir_old="arch/arm/plat-omap/include/mach"
plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)

omap: Split OMAP2_IO_ADDRESS to L3 and L42009-10-19T22:25:31+00:00Santosh Shilimkarsantosh.shilimkar@ti.com2009-10-19T22:25:31+00:00urn:sha1:233fd64e7f42a7b8e827ee02528474e0fabfebdc
This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and
OMAP2_L4_IO_ADDRESS to reclaim more IO space.
The omap_read*() and omap_write*() functions will work only over
L4 address space. Current omap kernel stack uses these functions
only to access registers over L4 io address space
Note that these macros should only be used when ioremap does
not work. Please use ioremap instead in all new code.

OMAP: Remove OMAP_IO_ADDRESS, use OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS instead2009-08-28T17:50:33+00:00Tony Lindgrentony@atomide.com2009-08-28T17:50:33+00:00urn:sha1:941132606c7611246d2034cb7b01f9270c2d1ede
Search and replace OMAP_IO_ADDRESS with OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS,
and convert omap_read/write into a functions instead of a macros.
Also rename OMAP_MPUIO_VBASE to OMAP1_MPUIO_VBASE.
In the long run, most code should use ioremap + __raw_read/write instead.

OMAP3 SDRC: add support for 2 SDRAM chip selects2009-07-25T01:43:25+00:00Jean Pihetjpihet@mvista.com2009-07-25T01:43:25+00:00urn:sha1:58cda884ecc87dcce18d463b0c8bd928dae63ad8
Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2
SDRAM parts connected to the SDRC.
This patch adds the following:
- add a new argument of type omap_sdrc_params struct*
to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params
- adapted the OMAP boards files to the new prototype of
omap2_init_common_hw
- add the SDRC 2nd CS registers offsets defines
- adapt the sram sleep code to configure the SDRC for the 2nd CS
Note: If the 2nd param to omap2_init_common_hw is NULL, then the
parameters are not programmed into the SDRC CS1 registers
Tested on 3430 SDP and Beagleboard rev C2 and B5, with
suspend/resume and frequency changes (cpufreq).

[ARM] OMAP2 SDRC: add SDRAM timing parameter infrastructure2009-02-08T17:50:39+00:00Paul Walmsleypaul@pwsan.com2009-01-28T19:27:39+00:00urn:sha1:87246b7567f7d1951bfcea29875523ef435c0ebf
For a given SDRAM clock rate, SDRAM chips require memory controllers
to use a specific set of timing minimums and maximums to transfer data
reliably. These parameters can be different for different memory chips
and can also potentially vary by board.
This patch adds the infrastructure for board-*.c files to pass this
timing data to the SDRAM controller init function. The timing data is
specified in an 'omap_sdrc_params' structure, in terms of SDRC
controller register values. An array of these structs, one per SDRC
target clock rate, is passed by the board-*.c file to
omap2_init_common_hw().
This patch does not define the values for different memory chips, nor
does it use the values for anything; those will come in subsequent patches.

[ARM] OMAP2 SDRC: separate common OMAP2/3 code from OMAP2xxx code2009-02-08T17:50:39+00:00Paul Walmsleypaul@pwsan.com2009-01-28T19:27:37+00:00urn:sha1:f2ab99778a1a04ddbae38f4de4ef40f2edb92080
Separate SDRC code common to OMAP2/3 from mach-omap2/sdrc2xxx.c to
mach-omap2/sdrc.c. Rename the OMAP2xxx-specific functions to use an
'omap2xxx' prefix rather than an 'omap2' prefix, and use "sdrc" in the
function names rather than "memory." Mark several functions
as static that should not be used outside the sdrc2xxx.c file.

ARM: OMAP3: Add minimal omap3430 support2008-10-09T14:51:41+00:00Syed Mohammed, Khasimkhasim@ti.com2008-10-09T14:51:41+00:00urn:sha1:cc26b3b01bc96a8b8c36671b0dc4898b2a152ea8
Add minimal omap3430 support based on earlier patches from
Syed Mohammed Khasim. Also merge in omap34xx SRAM support
from Karthik Dasu and use consistent naming for sram init
functions.
Also do following changes that make 34xx support usable:
- Remove unused sram.c functions for 34xx
- Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally
in entry-macro.S
- Update mach-omap2/io.c to support 2420, 2430, and 34xx
- Also merge in 34xx GPMC changes to add fields wr_access and
wr_data_mux_bus from Adrian Hunter
- Remove memory initialization call omap2_init_memory() until
until more generic memory initialization patches are posted.
It's OK to rely on bootloader initialization until then.

Misc updates from linux-omap tree, mostly to update common
device initialization and add missing defines from linux-omap
tree. Also some changes to make room for adding 34xx in
following patches.
Note that the I2C resources are now set up in
arch/arm/plat-omap/i2c.c helper, and can be removed
from devices.c.
