* SPEAr: Eliminate dependency on Xloader tableAmit Virdi2012-07-072-74/+0
| | | | | | | | | | Xloader table was used primarily to inform u-boot about the DDR size. However, now the ddr size is calculated at runtime which eliminates any need for the Xloader table. So removing this unnecessary code. Signed-off-by: Amit Virdi <amit.virdi@st.com> Acked-by: Stefan Roese <sr@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>
* st_smi: Add support for SPEAr SMI driverVipin KUMAR2012-07-071-115/+0
| | | | | | | | | | | | | | SMI is the serial memory interface controller provided by ST. Earlier, a driver exists in the u-boot source code for the SMI IP. However, it was specific to spear platforms. This commit converts the same driver to a more generic driver. As a result, the driver files are renamed to st_smi.c and st_smi.h and moved into drivers/mtd folder for reusability by other platforms using smi controller peripheral.

* ARM: OMAP4+: Move external phy initialisations to arch specific place.SRICHARAN R2012-07-071-0/+2
| | | | | | | | | | The external phy is present in the case OMAP5 soc is currently configured in emif-common.c. This results in having dummy structures for those Socs which do not have a external phy. So by having a weak function in emif-common and overriding it in OMAP5, avoids the use of dummy structures.

* omap: am33xx: accomodate input clocks other than 24 MhzSteve Sakoman2012-07-071-5/+5
| | | | | | | | | The PLL setup values currently assume a 24 Mhz input clock. This patch uses V_OSCK from the board config file to support boards with different input clock rates. Signed-off-by: Steve Sakoman <steve@sakoman.com>
* OMAP4+: Force DDR in self-refresh after warm resetLokesh Vutla2012-07-072-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Errata ID:i727 Description: The refresh rate is programmed in the EMIF_SDRAM_REF_CTRL[15:0] REG_REFRESH_RATE parameter taking into account frequency of the device. When a warm reset is applied on the system, the OMAP processor restarts with another OPP and so frequency is not the same. Due to this frequency change, the refresh rate will be too low and could result in an unexpected behavior on the memory side. Workaround: The workaround is to force self-refresh when coming back from the warm reset with the following sequence: • Set EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE to 0x2 • Set EMIF_PWR_MGMT_CTRL[7:4] REG_SR_TIM to 0x0 • Do a dummy read (loads automatically new value of sr_tim) This will reduce the risk of memory content corruption, but memory content can't be guaranteed after a warm reset. This errata is impacted on OMAP4430: 1.0, 2.0, 2.1, 2.2, 2.3 OMAP4460: 1.0, 1.1 OMAP4470: 1.0 OMAP5430: 1.0 Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: R Sricharan <r.sricharan@ti.com> Signed-off-by: Senthilvadivu Guruswamy <svadivu@ti.com>

| | | | | | | | | | | | 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.

* kw_spi: support spi_claim/release_bus functionsValentin Longchamp2012-07-071-0/+11
| | | | | | | | | | | | | These two function nows ensure that the MPP is configured correctly for the SPI controller before any SPI access, and restore the initial configuration when the access is over. Since the used pins for the SPI controller can differ (2 possibilities for each signal), the used pins are configured with CONFIG_SYS_KW_SPI_MPP.

* kirkwood: add save functionality kirkwood_mpp_conf functionValentin Longchamp2012-07-071-1/+1
| | | | | | | | | | | | | | If a second non NULL argument is given to the kirkwood_mpp_conf function, it will be used to store the current configuration of the MPP registers. mpp_save must be a preallocated table of the same size as mpp_list and it must be zero terminated as well. A later call to kirkwood_mpp_conf function with this saved list as first (mpp_conf) argment will set the configuration back.
