* omap3: Fixed a problem with hweccBen Goska2009-08-18-2/+2
| | | | | | | | In commit 187af954cf7958c24efcf0fd62289bbdb4f1f24e there was a typo that offset all the ecc registers by 4 bytes, fixed that. Signed-off-by: Ben Goska <goskab@onid.oregonstate.edu> Acked-by: Dirk Behme <dirk.behme@googlemail.com>
* OMAP3: Fix missing GPMC_CONFIG_CS0_BASEDirk Behme2009-08-10-0/+1
| | | | | | | | | | 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.

* omap3: use only fixed-size types inside ctrl_structsDirk Behme2009-08-08-194/+218
| | | | | | | | | | 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.

* OMAP3 Port kernel omap gpio interface.Tom Rix2009-06-12-0/+86
| | | | | | | | | Port version 2.6.27 of the linux kernel's omap gpio interface to u-boot. The orignal source is in linux/arch/arm/plat-omap/gpio.c See doc/README.omap3 for instructions on use. Signed-off-by: Tom Rix <Tom.Rix@windriver.com>
* OMAP3: Print correct silicon revisionSanjeev Premi2009-04-29-5/+9
| | | | | | | | | | The function display_board_info() displays incorrect silicon revision - based on the return value from function get_cpu_rev(). This patch fixes the problem. Signed-off-by: Sanjeev Premi <premi@ti.com>
* OMAP3: Remove unused board-typesSanjeev Premi2009-04-29-11/+0
| | | | | | | | | | | 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>
* OMAP3: Use functions print_cpuinfo() and checkboard()Sanjeev Premi2009-04-29-1/+0
| | | | | | | | | | | | | | | 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>

* OMAP3: Beagle: Add board revision detectionDirk Behme2009-02-22-1/+2
| | | | | | | | | | | | | | | | | | 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>
