* omap: Enable GPMC clock in gpmc_initOlof Johansson2010-01-201-0/+2
| | | | | | | | | | | | Don't assume that gpmc_l3_clk is on, enable it before touching configuration registers. Note that the current code assumes that this clock is always enabled. We are already setting smart idle and L3 autogating for GPMC clock in gpmc_init. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP4: Add minimal support for omap4Santosh Shilimkar2009-05-281-0/+6
| | | | | | | | | | | | This patch adds the support for OMAP4. The platform and machine specific headers and sources updated for OMAP4430 SDP platform. OMAP4430 is Texas Instrument's SOC based on ARM Cortex-A9 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency.

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.

| * [ARM] omap: Fix IO_ADDRESS() macrosRussell King2008-09-051-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies for use with __raw_{read|write}* for accessing registers. Therefore, these macros should return (void __iomem *) cookies, not integer values. Doing this improves typechecking, and means we can find those places where, eg, DMA controllers are incorrectly given virtual addresses to DMA to, or physical addresses are thrown through a virtual to physical address translation.

* ARM: OMAP2: Change 24xx to use new register accessPaul Walmsley2008-04-141-5/+7
| | | | | | | | | | | | | | | | | | | This patch changes 24xx to use new register access, except for clock framework. Clock framework register access will get updates in the next patch. Note that board-*.c files change GPMC (General Purpose Memory Controller) access to use gpmc_cs_write_reg() instead of accessing the registers directly. The code also uses gpmc_fck instead of it's parent clock core_l3_ck for GPMC clock. The H4 board file also adds h4_init_flash() function, which specify the flash start and end addresses. Also note that sleep.S removes some unused registers addresses. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP: omap2/gpmc updatesDavid Brownell2007-09-201-11/+22
| | | | | | | | | | | | | | | | | GPMC updates: - bugfixes: wrong/missing flags, omitted write, wrong test - don't map memory segments starting at zero - improve debug messaging - export gpmc_get_fclk_perio]d() since it's needed to calc timings - expect gpmc_cs_set_timings() caller to have initialized sync vs async Note that this API is glitchy; likely the best fix would be to add a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that holds one key aspect of the GPMC timings (the gpmc_fclk divisor, and sync vs. async == whether that divisor matters).
