* ARM: OMAP4/5: Move USB pads to essential list.SRICHARAN R2012-07-07-13/+12
| | | | | | | | | USB module pads are getting enabled under non-essential group. These will be required for fastboot, tftp support. So move this to essential list to have them working when non-essential pads are no more muxed. Signed-off-by: R Sricharan <r.sricharan@ti.com>
* OMAP4460: TPS Ensure SET1 is selected after voltage configurationNishanth Menon2012-05-15-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | TPS SET0/SET1 register is selected by a GPIO pin on OMAP4460 platforms. Currently we control this pin with a mux configuration as part of boot sequence. Current configuration results in the following voltage waveform: |---------------| (SET1 default 1.4V) | --------(programmed voltage) | <- (This switch happens on mux7,pullup) vdd_mpu(TPS) -----/ (OPP boot voltage) --------- (programmed voltage) vdd_core(TWL6030) -----------------------/ (OPP boot voltage) Problem 1) |<----- Tx ------>| timing violation for a duration Tx close to few milliseconds. Problem 2) voltage of MPU goes beyond spec for even the highest of MPU OPP. By using GPIO as recommended as standard procedure by TI, the sequence changes to: -------- (programmed voltage) vdd_mpu(TPS) ------------/ (Opp boot voltage) --------- (programmed voltage) vdd_core(TWL6030) -------------/ (OPP boot voltage) NOTE: This does not attempt to address OMAP5 - Aneesh please confirm Reported-by: Isabelle Gros <i-gros@ti.com> Reported-by: Jerome Angeloni <j-angeloni@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com>
* ARM:OMAP+:MMC: Add parameters to MMC initJonathan Solnit2012-05-15-2/+2
| | | | | | | | | | 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>
* omap4460: fix TPS initializationAneesh V2011-12-06-1/+12
| | | | | | | | | | | TPS power IC is controlled using a GPIO (gpio_wk7). This GPIO should be maintained at logic 1 always. As such an internal pull-up on this pin will do the job, driving the GPIO outuput is not needed. This will avoid the need of using GPIO library in SPL and also may save some power.

* omap4/5: Add support for booting with CH.Sricharan2011-11-15-8/+9
| | | | | | | | | | | | | | | | Configuration header(CH) is 512 byte header attached to an OMAP boot image that will help ROM code to initialize clocks, SDRAM etc and copy U-Boot directly into SDRAM. CH can help us in by-passing SPL and directly boot U-boot, hence it's an alternative for SPL. However, we intend to support both CH and SPL for OMAP4/5. Initialization done through CH is limited and is not equivalent to that done by SPL. So U-Boot has to distinguish between the two cases and handle them accordingly. This patch takes care of doing this. Signed-off-by: sricharan <r.sricharan@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap5: Add minimal support for omap5430.Sricharan2011-11-15-3/+80
| | | | | | | | | | | | | | | | This patch adds the minimal support for OMAP5. The platform and machine specific headers and sources updated for OMAP5430. OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency. Also moved some part of code from the basic platform support that can be made common for OMAP4/5. Rest is kept out seperately. The same approach is followed for clocks and emif support in the subsequent patches. Signed-off-by: sricharan <r.sricharan@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* 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>

| | | | | | | | | | | | | - Provide alternate implementations of board_init_f() board_init_r() for OMAP spl. - Provide linker script - Initialize global data - Add serial console support - Update CONFIG_SYS_TEXT_BASE to allow for SPL's bss and move it to board config header from config.mk Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap4: cleanup pin mux dataAneesh V2011-08-03-74/+27
| | | | | | | | | | | | | - separate mux settings into essential and non essential parts - essential part is board independent as of now(so move it to SoC directory). Will help in having single SPL for all boards. - Non-essential part(the pins not essential for u-boot to function) need to be phased out eventually. - Correct mux data by aligning to the latest settings in x-loader Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* 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>
* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-1/+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: Add support for TI OMAP4430 SDPSteve Sakoman2010-07-05-0/+143
OMAP4430 SDP is a reference board based on OMAP4430, an ARMV7 Cortex A9 CPU This patch adds basic support for booting the board. It includes i2c and mmc support. It assumes U-boot is loaded to SDRAM with the help of another small bootloader (x-load) running from SRAM.
