2009-11-27OMAP3: Fix SDRC initNishanth Menon
Defaults are for Infineon DDR timings. Since none of the supported boards currently do XIP boot, these seem to be faulty. fix the values as per the calculations(ACTIMA,B), conf the sdrc power with pwdnen and wakeupproc bits Signed-off-by: Nishanth Menon <nm@ti.com>
2009-11-27OMAP3:SDRC: introduce DDR typesNishanth Menon

2009-11-16OMAP2/3: I2C: Add support for second and third busDirk Behme
Add support to use second and third I2C bus, too. Bus 0 is still the default, but by calling i2c_set_bus_num(1/2) before doing I2C accesses, code can switch to bus 1 and 2, too. Don't forget to switch back afterwards, then. Signed-off-by: Dirk Behme <dirk.behme@googlemail.com>
2009-10-24TI OMAP3: make gpmc_config as constNishanth Menon
gpmc_config should not be a variant as it is board specific hence make it a const parameter Fixes issues identified by Dirk: - build issue for zoom2 - warnings for all other OMAP3 platforms using nand/onenand etc Signed-off-by: Nishanth Menon <nm@ti.com>
2009-10-18OMAP3: export enable_gpmc_cs_config to board filesNishanth Menon
Export enable_gpmc_cs_config into common header to prevent warning: warning: implicit declaration of function 'enable_gpmc_cs_config' Signed-off-by: Nishanth Menon <nm@ti.com>

2009-10-13OMAP3 Move cache routine to cache.STom Rix
v7_flush_dcache_all, because it depends on omap ROM code is not generic. Rename the function to 'invalidate_dcache' and move it to the omap cpu directory. Collect the other omap cache routines l2_cache_enable and l2_cache_disable with invalide_dcache into cache.S. This means removing the old cache.c file that contained l2_cache_enable and l2_cache_disable. The conversion from cache.c to cache.S was done most through disassembling the uboot binary. The only significant change was to change the comparision for the return of get_cpu_rev from cmp r0, #0 beq earlier_than_label Which was lost information to cmp r0, #CPU_3XX_ES20 blt earlier_than_label The paths through the enable routine were verified by adding an infinite loop and seeing the hang. Then removing the infinite loop and seeing it continue. The disable routine is similar enough that it was not tested with this method. Run tested by cold booting from nand on beagle and zoom1. Compile tested on MAKEALL arm. Signed-off-by: Tom Rix <Tom.Rix@windriver.com>
2009-08-18omap3: Fixed a problem with hweccBen Goska

2009-08-10OMAP3: Fix missing GPMC_CONFIG_CS0_BASEDirk Behme
Applying two indepenent OMAP3 patches resulted in missing GPMC_CONFIG_CS0_BASE. Patch "omap3: embedd gpmc_cs into gpmc config struct" removes GPMC_CONFIG_CS0_BASE, independent patch "omap3: bug fix for NOR boot support" introduces it's usage. Re-introduce GPMC_CONFIG_CS0_BASE.

2009-08-08omap3: use only fixed-size types inside ctrl_structsDirk Behme
replace variable types in ctrl_structs for omap3 by those with fixed size (u8, u16, u32). Additional ifndef-protection is needed by examples which do not compile when including asm/types.h Signed-off-by: Matthias Ludwig <mludwig@ultratronik.de> Signed-off-by: Dirk Behme <dirk.behme@googlemail.com>

The prescalar that converts the function clock to the sampling clock is hardcoded to 0. The reference manual recommends 7 if the function clock is 96MHz. Instead of just changing the hardcoded values, the prescalar is calculated from the value I2C_IP_CLK. The i2c #defines are in kHz. The speed passed into the i2c init routine is in Hz. To be consistent, change the defines to be in Hz. The timing calculations are based on what is done in the linux 2.6.30 kernel in drivers/i2c/buses/i2c_omap.c as apposed to what is done in TRM. The major variables in the timing caculations are specified as #defines that can be overriden as required. The variables and their defaults are I2C_IP_CLK SYSTEM_CLOCK_96 I2C_INTERNAL_SAMPLING_CLK 19200000 I2C_FASTSPEED_SCLL_TRIM 6 I2C_FASTSPEED_SCLH_TRIM 6 I2C_HIGHSPEED_PHASE_ONE_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM I2C_HIGHSPEED_PHASE_ONE_SCLH_TRIM I2C_FASTSPEED_SCLH_TRIM I2C_HIGHSPEED_PHASE_TWO_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM I2C_HIGHSPEED_PHASE_TWO_SCLH I2C_FASTSPEED_SCLH_TRIM This was runtime verified on Zoom1, Zoom2, Beagle and Overo. The 400kHz and 3.4M cases were verifed on test Zoom1, Zoom2, Beagle and Overo configurations. Testing for omap2 will be done in a second step as Nishanth and Jean-Christophe commented.

2009-04-29OMAP3: Remove unused board-typesSanjeev Premi
The board-types defined in struct omap3_sysinfo seem to be unused. The function display_board_info() is passed board type as an argument; which is ignored. This patch removes all uses of board-type, related definitions and functions. Signed-off-by: Sanjeev Premi <premi@ti.com>
2009-04-29OMAP3: Use functions print_cpuinfo() and checkboard()Sanjeev Premi
Use the functions print_cpuinfo() and checkboard() to display the cpu and board specific information. These functions reuse content from the existing function display_board_info() - which has been removed. Also, updated the existig OMAP3 configurations to define: - CONFIG_DISPLAY_CPUINFO - CONFIG_DISPLAY_BOARDINFO Signed-off-by: Sanjeev Premi <premi@ti.com>

2009-02-22OMAP3: Beagle: Add board revision detectionDirk Behme
With BeagleBoard revision C some HW changes are introduced (e.g. PinMUX) which might need different software handling. For this, GPIO pin 171 (GPIO module 6, offset 11) can be used to check for board revision. If this pin is low, we have a rev C board. Else it must be a revision Ax or Bx board. To handle board differences you can call function beagle_get_revision(). E.g.: if (beagle_get_revision()) { /* do special revision C stuff here */ } Signed-off-by: Dirk Behme <dirk.behme@googlemail.com>
