* a/a/c/arm920t/at91/reset.c: drop obsolete CONFIG_AT91RM9200_USARTAndreas Bießmann2011-08-03-4/+0
| | | | | | | | The CONFIG_AT91RM9200_USART is an remnant of 18ed5e9550810e2fc5bf2c757aee47774609651c which deleted the at91rm9200_usart driver. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

* omap4: automatic sdram detectionAneesh V2011-08-03-0/+238
| | | | | | | | | | | | | | | | | | | | | | | | | Identify SDRAM devices connected to EMIF automatically: LPDDR2 devices have some Mode Registers that provide details about the device such as the type, density, bus width etc. EMIF has the capability to read these registers. If there are no devices connected to a given chip-select reading mode registers will return junk values. After reading as many such registers as possible and matching with expected ranges of values the driver can identify if there is a device connected to the respective CS. If we identify that a device is connected the values read give us complete details about the device. This along with the base AC timings specified by JESD209-2 allows us to do a complete automatic initialization of SDRAM that works on all boards. Please note that the default AC timings specified by JESD209-2 will be safe for all devices but not necessarily optimal. However, for the Elpida devices used on Panda and SDP the default timings are both safe and optimal. Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap4: calculate EMIF register valuesAneesh V2011-08-03-10/+967
| | | | | | | | | | | | | | Calculate EMIF register values based on AC timing parameters from the SDRAM datasheet and the DDR frequency rather than using the hard-coded values. For a new board the user doen't have to go through the tedious process of calculating the register values. Instead, just provide the AC timings from the device data sheet as input and the driver will automatically calculate the register values.

* omap4: cleanup pin mux dataAneesh V2011-08-03-4/+129
| | | | | | | | | | | | | - 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>
* omap4: utility function to identify the context of hw initAneesh V2011-08-03-1/+82
| | | | | | | | | | | | | | | | The basic hardware init of OMAP4(s_init()) can happen in 4 different contexts: 1. SPL running from SRAM 2. U-Boot running from FLASH 3. Non-XIP U-Boot loaded to SDRAM by SPL 4. Non-XIP U-Boot loaded to SDRAM by ROM code using the Configuration Header feature What level of hw initialization gets done depends on this context. Add a utility function to find this context. Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* DA8xx: fix LPSC constantsLaurence Withers2011-08-03-12/+31
| | | | | | | | | | Some of the LPSC constants were incorrect, and some were missing.

| | | | | | | | | | There are two main sets of LPSC constants, depending on the processor family. The DA8xx constants were given in an enum whereas the non-DA8xx constants were preprocessor defines.

* DaVinci EMAC: declare function for all DA8xx CPUsLaurence Withers2011-08-03-1/+1
| | | | | | | | | | | | The function davinci_emac_mii_mode_sel() is defined in board/davinci/common/misc.c for any DA8xx CPU which has CONFIG_DRIVER_TI_EMAC enabled. However, the prototype was only being declared in <include/asm/arch/davinci_misc.h> for the DA850 EVM board. This patch declares it for all DA8xx CPUs where CONFIG_DRIVER_TI_EMAC is enabled.
