2015-06-08ot1200: setup i2c bus 1 in setup_iomux_i2c()Christian Gmeiner1-0/+15
On this bus there is a EEPROM containing EDID and ddr3 calibration information. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2015-06-08ot1200: setup i2c bus in board_early_init_f(..)Christian Gmeiner1-18/+22
Make it possible to use the i2c bus in SPL. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2015-01-22ot1200: add basic SPL supportChristian Gmeiner2-0/+166
Currently we only support the Micron MT41K128M16JT-125 ddr3 chip. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>

2015-01-22ot1200: move ccgr and gpr init to c functionsChristian Gmeiner2-14/+28
We need this way for SPL boot. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2015-01-22ot1200: make use of imx_ddr_size(..)Christian Gmeiner1-1/+2
To support different ddr3 memory sizes we should start using imx_ddr_size(..) instead of the define PHYS_SDRAM_SIZE. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2014-11-24ot1200: Fix error handling in board_mmc_init()Fabio Estevam1-4/+6
When an invalid USDHC port is passed we should return -EINVAL instead of 0. Also, return the error immediately on fsl_esdhc_initialize() failure. Cc: Christian Gmeiner <christian.gmeiner@gmail.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
2014-11-13ot1200: fix card detect for usdhc4Christian Gmeiner1-2/+2
Today I got the final board and found out that a different connector is used as the one on my development board. The new connector has swaped pins for cd and wp. This change is tested on a production ready board. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>

2014-10-30ot1200: add support for usdhc4Christian Gmeiner1-5/+49
On the 'mr' variant switching to 'mmc dev 1' will result in "MMC: no card present". Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2014-10-30ot1200: add feature padsChristian Gmeiner1-0/+15
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 Savoundararadj1-3/+0
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.

One of the possible boot devices can be sata. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2014-10-23ot1200: fix sf detectionChristian Gmeiner1-0/+5
Commit 155fa9af95ac5be857a7327e7a968a296e60d4c8 changed the way to define a GPIO line, which can be used to force CS high across multiple transactions. In order to fix sf detection change board code to make use of board_spi_cs_gpio(..).
