* Pass sdrc timing values through board_sdrc_timings structurePeter Barada2012-12-10-19/+18
| | | | | | | | | Instead of passing individual registers by value to board_get_mem_timings, pass a board_mem_timings structure pointer for the board files to fill in. Pass same structure pointer to write_sdrc_timings. This saves about 90 bytes of space in SPL. Signed-off-by: Peter Barada <peter.barada@logicpd.com>
* omap-common: SPL: Add CONFIG_SPL_DISPLAY_PRINT / spl_display_print()Tom Rini2012-09-27-10/+0
| | | | | | | | Only omap4/5 currently have a meaningful set of display text and overo had been adding a function to display nothing. Change how this works to be opt-in and only turned on for omap4/5 now. Signed-off-by: Tom Rini <trini@ti.com>
* ARM:OMAP+:MMC: Add parameters to MMC initJonathan Solnit2012-05-15-1/+1
| | | | | | | | | | Add parameters to the OMAP MMC initialization function so the board can mask host capabilities and set the maximum clock frequency. While the OMAP supports a certain set of MMC host capabilities, individual boards may be more restricted and the OMAP may need to be configured to match the board. The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example. Signed-off-by: Jonathan Solnit <jsolnit@gmail.com>

* omap: Don't use gpio_free to change direction to inputJoe Hershberger2011-10-27-6/+1
| | | | | | | | | gpio_free() should not have the side effect of setting the line to input since this prevents the gpio command from being able to set a line as output.

* OMAP3: overo: Move ethernet CS4 configuration to execute based on board idPhilip Balister2011-10-27-4/+3
| | | | | | | | | | | By moving the CS4 configuration into the board specific configuration, it is left free for custom carrier boards. The USRP-E1XX series uses CS4 to control access to an FPGA, so without this patch the device driver cannot claim CS4.

* omap: overo: Disable pull-ups on camera PCLK, HS and VS signalsSteve Sakoman2011-10-27-3/+3
| | | | | | | | | | | | | The level shifters used on the Caspa camera module have a 4k output impedance. Combined with the 100uA pull-up resistors in the OMAP3, this raises the ground level to 400mV. Adding crosstalk between the pixel clock and the HS/VS signals on the flat cable (a ground line in between would have been nice), logic 0 levels can raise up to 650mV. This exceeds the camera input pins VIL maximum voltage. This change suggested-by Laurent Pinchart Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap: overo: Configure mux for gpio10Steve Sakoman2011-10-27-1/+1
| | | | | | | | | | This pad was previously configured for sysclkout_1. This patch changes the configuration to gpio_10 to reduce radiated noise from the 26Mhz clock, as well as make the pin more generally useful.

* punt unused clean/distclean targetsMike Frysinger2011-10-15-6/+0
| | | | | | | | | | The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all. MAKEALL didn't report any errors related to this that I could see. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* overo: Set IEN on GPMC_CLK to support synchronous clocking.Philip Balister2011-09-30-1/+1

* OMAP3: Overo: Update GPMC timing for ethernet chipPhilip Balister2011-09-30-9/+1
| | | | | | | | | | The existing timing does not quite meet the minimum requirements in the LAN9221 datasheet. The timing in this patch solves problems noticed on some parts. The patch also combines the CS configuration for the overo and igep0020 boards per request. Signed-off-by: Philip Balister <philip@opensdr.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* Move DECLARE_GLOBAL_DATA_PTR to file scopeJohn Rigby2010-12-21-2/+2
| | | | | | | | | | | | | | | It can be optimised out by the compiler otherwise resulting in obscure errors like a board not booting.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* ARMV7: OMAP3: Add expansion board detection for OveroSteve Sakoman2010-11-04-0/+119
| | | | | | | | | | Overo expansion boards contain an i2c eeprom to identify themselves. This patch adds code to read and parse the eeprom contents. It prints the expansion board name and revision and modifies environment variables as appropriate. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-2/+1
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* ARMV7: OMAP: Overo: Autodetect presence/absence of transceiver on mmc2Steve Sakoman2010-09-08-2/+80
| | | | | | | | | | An upcoming version of Overo uses a Wifi/BT module with 1.8V signaling, eliminating the need for an external transceiver to handle the level shifting. This patch detects whether an external transceiver is present and adjusts the pinmux settings as appropriate.

* ARMV7: OMAP: Add board revision detection for OveroSteve Sakoman2010-09-08-3/+35
| | | | | | | | | | | The latest Overo COM modules encode their revision number on GPIOs 115, 113, and 112. All boards to date have no pullups on these pins and hence appear as revision 0. This patch reads and prints the revision information. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* ARMV7: OMAP: Enable input driver on Overo's MMC1_CLK and MMC3_CLK pinmux setupSteve Sakoman2010-09-08-2/+2

* TWL4030: make LEDs selectable for twl4030_led_init()Grazvydas Ignotas2010-01-04-1/+1
| | | | | | | | | | | | Not all boards have both LEDs hooked, so enabling both on boards with single LED will just waste power. Make it possible to choose LEDs by adding argument to twl4030_led_init(). Using this turn on only LEDB for pandora, leave both LEDs on for all other boards, as it was before this patch.

* TI: OMAP3: Overo Tobi ethernet supportOlof Johansson2009-10-13-31/+91
| | | | | | | | | | | | | Add setup for ethernet on Tobi, allowing kernel/ramdisk to be loaded over tftp. This also refactors the smc911x driver to allow for detecting when the chip is missing. I.e. the detect_chip() function is called earlier and will abort gracefully when the Chip ID read returns all 1's.
