* ARM: DRA7/OMAP5: EMIF: Add workaround for bug 0039SRICHARAN R2013-12-04-1/+124
| | | | | | | | | | | When core power domain hits oswr, then DDR3 memories does not come back while resuming. This is because when EMIF registers are lost, then the controller takes care of copying the values from the shadow registers. If the shadow registers are not updated with the right values, then this results in incorrect settings while resuming. So updating the shadow registers with the corresponding status registers here during the boot. Signed-off-by: Sricharan R <r.sricharan@ti.com>
* ARM: DRA: EMIF: Change DDR3 settings to use hw levelingSRICHARAN R2013-12-04-98/+174
| | | | | | | | | | Currently the DDR3 memory on DRA7 ES1.0 evm board is enabled using software leveling. This was done since hardware leveling was not working. Now that the right sequence to do hw leveling is identified, use it. This is required for EMIF clockdomain to idle and come back during lowpower usecases.

* am33xx: Stop modifying certain EMIF4D registersTom Rini2013-12-04-32/+6
| | | | | | | | | | | | | | | Based on the definitive guide to EMIF configuration[1] certain registers that we have been modifying (and are documented registers) should be left in their reset values rather than modified. This has been tested on AM335x GP EVM and Beaglebone White.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h

This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change from 0x64656465 to 0x64646464 is to remove the weak pull enabled on DQS, nDQS lines. This pulls the differential signals in the same direction which is not intended. So disabling the weak pulls improves signal integrity. On the uEVM there are 4 DDR3 devices. The VREF for 2 of the devices is powered by the OMAP's VREF_CA_OUT pins. The VREF on the other 2 devices is powered by the OMAP's VREF_DQ_OUT pins. So the net effect here is that only half of the DDR3 devices were being supplied a VREF! This was clearly a mistake. The second change improves the robustness of the interface and was specifically seen to cure corruption observed at high temperatures on some boards. With the above two changes better memory stability was observed with extended temperature ranges around 100C. Signed-off-by: Sricharan R <r.sricharan@ti.com>
