2013-06-10ARM: DRA7xx: EMIF: Change settings required for EVM boardSricharan R
DRA7 EVM board has the below configuration. Adding the settings for the same here. 2Gb_1_35V_DDR3L part * 2 on EMIF1 2Gb_1_35V_DDR3L part * 4 on EMIF2 Signed-off-by: Sricharan R <r.sricharan@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2013-03-11arm: dra7xx: Add DDR related data for DRA752 ES1.0Lokesh Vutla
DRA752 uses DDR3. Populating the corresponding structures with DDR3 data. Writing into MA registers if only MA is present in that soc. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: R Sricharan <r.sricharan@ti.com> Reviewed-by: Tom Rini <trini@ti.com>
2013-03-11ARM: OMAP5: Add DDR changes required for OMAP543X ES2.0 SOCsLokesh Vutla
Add pre calculated timing settings of LPDDR2 and DDR3 memories present in OMAP5430 and OMAP5432 ES2.0 versions. Also adding the DDR pad io settings required for OMAP543X SOCs here.

2013-03-11ARM: OMAP4+: Cleanup emif specific filesLokesh Vutla
Removing the duplicated code in ddr3 initialization. Also creating structure for lpddr2 mode registers to avoid unnessecary revision checks. These change reduces code addition for future Socs.

2012-07-07ARM: OMAP4+: Move external phy initialisations to arch specific place.SRICHARAN R
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. Signed-off-by: R Sricharan <r.sricharan@ti.com>

2012-07-07ARM: OMAP5: dmm: Create a tiler trap section.SRICHARAN R
The unmapped entries in tiler space are set with values 0xFF. So creating a DMM section of size 16MB at 0xFF000000 with ADDRSPACE set to 0x2. This way all the unmapped entry accesses to tiler will be trapped by the EMIF and a error response is sent to the L3 interconnect. L3 errors are inturn reported to MPU. Note that here the tiler trap section is overlapping with the actual ddr physical space and we lose 16MB out of the total 2GB. Signed-off-by: R Sricharan <r.sricharan@ti.com>

The ddr part name used in OMAP5 ES1.0 soc is a SAMSUNG part and not a ELPIDA part. So change this. Signed-off-by: R Sricharan <r.sricharan@ti.com>
