2016-09-06mx6: ddr: Allow changing REFSEL and REFR fieldsFabio Estevam
Currently MX6 SPL DDR initialization hardcodes the REF_SEL and REFR fields of the MDREF register as 1 and 7, respectively for DDR3 and 0 and 3 for LPDDR2. Looking at the MDREF initialization done via DCD we see that boards do need to initialize these fields differently: $ git grep 0x021b0020 board/ board/bachmann/ot1200/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/ccv/xpress/imximage.cfg:DATA 4 0x021b0020 0x00000800 /* MMDC0_MDREF */ board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x7800 board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6qp.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6dlsabresd.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6slevk/imximage.cfg:DATA 4 0x021b0020 0x00001800 board/freescale/mx6sxsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/freescale/mx6sxsabresd/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800 So introduce a mechanism for users to be able to configure REFSEL and REFR fields as needed.

2014-10-30ot1200: add feature padsChristian Gmeiner
The older 'mr' variant and the generic variant of the OT1200 differ in some places. As the name suggests the generic variant supports more boot devices. In order to be compatible with the 'mr' variant we define some 'feature' GPIOs. On the 'mr' variant this pads are not connected so we define their state with the help of the internal pullups. On the generic variant this GPIOs are connected and represent the state of the hardware. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2014-10-29kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj
This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.
