2012-10-25am335x: Enable RTC 32K OSC clockVaibhav Hiremath
In order to support low power state, you must source kernel system timers to persistent clock, available across suspend/resume. In case of AM335x device, the only source we have is, RTC32K, available in wakeup/always-on domain. Having said that, during validation it has been observed that, RTC clock need couple of seconds delay to stabilize the RTC OSC clock; and such a huge delay is not acceptable in kernel especially during early init and also it will impact quick/fast boot use-cases. So, RTC32k OSC enable dependency has been shifted to SPL/first-bootloader. Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Tom Rini <trini@ti.com>
2012-09-01am33xx evm: Update secure_emif_sdram_config during ddr initSatyanarayana, Sandhya
This patch updates secure_emif_sdram_config with the same value written to sdram_config during ddr3 initialization. During suspend/resume, this value is copied into sdram_config. With this, a write to sdram_config at the end of resume sequence which triggers an init sequence can be avoided. Without this register write in place, the DDR_RESET line goes low for a few cycles during resume which is a violation of the JEDEC spec.

2012-09-01am33xx: CPSW init and definitionsChandan Nath
This patch adds platform-specific initialization for CPSW switch on TI AM33XX SoCs. Signed-off-by: Chandan Nath <chandan.nath@ti.com> [Ilya: split init out of original patch] Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>
2012-09-01omap: am33xx: enable gpio supportSteve Sakoman
This patch uses the code in omap-common to support gpio modules 1-3 on am33xx based boards. It adds base address and register definitions, enables clocks to the modules, and enables building the common gpio code for CONFIG_AM33XX as well as CONFIG_OMAP Signed-off-by: Steve Sakoman <steve@sakoman.com>
2012-07-07ARM: OMAP3+: Detect reset typeLokesh Vutla
Certain modules are not affected by means of a warm reset and need not be configured again. Adding an API to detect the reset reason warm/cold. This will be used to skip the module configurations that are retained across a warm reset. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: R Sricharan <r.sricharan@ti.com>

2012-07-07am33xx: Do not call init_timer twiceTom Rini
We do not need to call init_timer both in SPL and U-Boot itself, just SPL needs to initialize the timer. Signed-off-by: Tom Rini <trini@ti.com>
