2011-12-06AM35xx: add EMAC supportIlya Yanok
AM35xx has DaVinci-compatible EMAC. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
2011-12-06arm926ejs: add noop implementation for dcache opsIlya Yanok
Added noop implementation for dcache operations that will buzz about missing real implementation and disable the dcache. This fixes compilation of DaVinci EMAC driver on arm926ejs. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
2011-12-06davinci_emac: move arch-independent defines to separate headerIlya Yanok
DaVinci EMAC is found not only on DaVinci SoCs but on some OMAP3 SoCs also. This patch moves common defines from arch-davinci/emac_defs.h to drivers/net/davinci_emac.h DaVinci specific PHY drivers hacked to include the new header. We might want to switch to phylib in future.

2011-12-06omap4: fix IO settingAneesh V
The value from TRIM is not working for some 4430 silicons. So, override with hw team recommended value. However, for 4460 TRIM value shall be used as long as the part is trimmed This fixes boot problem on some OMAP4430 ES2.0 Panda boards out there.

2011-12-06omap4: emif: fix error in driverAneesh V
There was a typo in the EMIF driver. It went un-noticed because it affected only when automatic detection is enabled and even then half the memory was configured and identified properly. Reported-by: Rockefeller <rockefeller.lin@innocomm.com> Signed-off-by: Aneesh V <aneesh@ti.com>
2011-12-06omap: remove I2C from SPLAneesh V
Due to some recent changes I2C is no longer required in SPL. Remove the i2c_init() call to save some space Signed-off-by: Aneesh V <aneesh@ti.com>
2011-12-06omap4460: fix TPS initializationAneesh V
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. Signed-off-by: Aneesh V <aneesh@ti.com>

2011-12-06armv7: include armv7/cpu.c in SPL buildAneesh V
This allows SPL to have default implementation of save_boot_params(), useful for SoCs that do not intend to override this default implementation Cc: Albert Aribaud <albert.u.boot@aribaud.net> Signed-off-by: Aneesh V <aneesh@ti.com>
2011-12-06armv7: disable L2 cache in cleanup_before_linux()Aneesh V
We were not disabling external caches before jumping to kernel. We were flushing all caches including external caches and disabling caches globally in CP15 System Control register. Apparently this is not enough. The bootstrap loader in Linux kernel that does decompression enables data-caches again, flush them after use and disable them before jumping to kernel proper. However, it's not aware of the external caches. Since we have left external cache enabled, external cache will get used once caches are enabled globally, but it's not flushed because decompressor is not aware of external caches. When it jumps to kernel with caches disabled globally, we have stale data in the external cache and a coherency problem. This was breaking the boot for OMAP4 with latest mainline kernel. The solution is to disable external caches in cleanup_before_linux(). With this fix kernel is booting again. Cc: Albert Aribaud <albert.u.boot@aribaud.net> Signed-off-by: Aneesh V <aneesh@ti.com>

2011-11-15omap4/5: Add support for booting with CH.Sricharan
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>

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.

2011-11-11iMX28: Fix ARM vector handlingMarek Vasut
This patch introduces proper ARM vector handling for i.MX28 CPU. This issue wasn't addressed because the interrupts weren't enabled on any ARMv5 core, therefore the issue wasn't noticed earlier. In previous implementation, the vectoring code used by i.MX28 CPU when an exception happened was that of the SPL. With this change, the branch target when an exception happens can be reconfigured by U-Boot.

2011-11-04mx53: Turn off child clocks before reconfigure perclk_rootFabio Estevam
In addition to ensuring that PERCLK remains at least 2.5 times slower than the AHB clock, certain steps need to be followed to ensure robust operation of PERCLK when reconfiguring the PERCLK clock source. To properly configure the PERCLK clock source, the following steps are required: 1.In the CCGR registers, gate the clocks to all PERCLK-dependent modules. 2.Select the desired input clock for the PERCLK root clock (to be either source from the peripherals main source clock or the lp_apm clock source). Refer to the CMCBR register, perclk_lp_apm_sel bit. 3.Configure the perclk_pred1, perclk_pred2, and perclk_podf dividers to the desired setting. Refer to the CBCDR register for details. 4.In the CCGR registers, enable the desired clocks for the PERCLK-dependent module clocks. If these steps aren't followed, GPT timer may stop and the kernel stops at "Calibrating delay loop".
