2014-04-23powerpc/T4QDS: add two stage boot of nand/sdShaohui Xie
Add support of 2 stage NAND/SD boot loader using SPL framework. PBL initialise the internal SRAM and copy SPL, this further initialise DDR using SPD and environment and copy u-boot from NAND/SD to DDR, finally SPL transfer control to u-boot. NOR uses CS1 instead of CS2 when NAND boot, fix it. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

2013-05-24powerpc/t4240qds: Add VDD overrideYork Sun
Allow VDD voltage overriding with a command. This is an add-on feasture of VID. To override VDD, use command vdd_override with the value of voltage in mV, for example vdd_override <voltage in mV, eg. 1050> The above example will set the VDD to 1.050 volt. Any wrong value out of range of 0.8188 to 1.2125 volt or invalid string is ignored. In addition to the command, if overriding VDD is needed earlier in booting process, save an variable and reboot: setenv t4240qds_vdd_mv <voltage in mV> saveenv Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
2012-10-22powerpc/t4qds: Add T4QDS boardYork Sun
The T4240QDS is a high-performance computing evaluation, development and test platform supporting the T4240 QorIQ Power Architecture™ processor. SERDES Connections 32 lanes grouped into four 8-lane banks Two “front side” banks dedicated to Ethernet Two “back side” banks dedicated to other protocols DDR Controllers Three independant 64-bit DDR3 controllers Supports rates up to 2133 MHz data-rate Supports two DDR3/DDR3LP UDIMM/RDIMMs per controller QIXIS System Logic FPGA Each DDR controller has two DIMM slots. The first slot of each controller has up to 4 chip selects to support single-, dual- and quad-rank DIMMs. The second slot has only 2 chip selects to support single- and dual-rank DIMMs. At any given time, up to total 4 chip selects can be used.
