* powerpc: Add P3041DS/P5020DS board support (uses corenet_ds code)Kumar Gala2011-04-27-3/+4
| | | | | | | | | | | | | | | | The P3041DS & P5020DS boards are almost identical (except for the processor in them). Additionally they are based on the P4080DS board design so we use the some board code for all 3 boards. Some ngPIXIS (FPGA) registers where reserved on P4080DS and now have meaning on P3041DS/P5020DS. We utilize some of these for SERDES clock configuration. Additionally, the P3041DS/P5020DS support NAND. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Shaohui Xie <b21989@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* p1022ds: allow for board-specific ngPIXIS functionsTimur Tabi2011-04-04-1/+7
| | | | | | | | | | | | | | | | The ngPIXIS is an FPGA used on the reference boards of most Freescale PowerPC SOCs. Although programming the ngPIXIS is mostly standard on all boards that have it, the P1022DS is unique in that the ngPIXIS needs to be programmed in "indirect" mode whenever the video display (DIU) is active. To support indirect mode, and to make it easier to support other quirks on future reference boards, the low-level ngPIXIS functions are all marked as weak, so that board-specific code can override any of them. We take advantage of this feature on the P1022DS, so that we can properly reset the board when the DIU is active.

* ppc/85xx: Add a structure defn for PIXIS registersKumar Gala2010-07-16-1/+1
| | | | | | | | | | | | | The various boards that have PIXIS FPGAs have slightly different register definitions, however there is some common functionality (like reset, ICS307 clk control, etc) that can be shared. The struct definition exists for MPC8536DS, MPC8544DS, MPC8572DS, MPC8610HPCD, and MPC8641HPCN boards. Also fixed ngpixis to be __packed__ instead of aligned.

* fsl: rename 'dma' to 'brdcfg1' in the ngPIXIS structureTimur Tabi2010-05-30-1/+1
| | | | | | | | | | The ngPIXIS is a board-specific FPGA, but the definition of the registers is mostly consistent. On boards where it matter, register 9 is called 'brdcfg1' instead of 'dma', so rename the variable in the ngpixis_t definition.

* p2020ds: add alternate boot bank support using the ngPIXIS FPGATimur Tabi2010-04-07-0/+57
The Freescale P2020DS board uses a new type of PIXIS FPGA, called the ngPIXIS. The ngPIXIS has one distinct new feature: the values of the on-board switches can be selectively overridden with shadow registers. This feature is used to boot from a different NOR flash bank, instead of having a register dedicated for this purpose. Because the ngPIXIS is so different from the previous PIXIS, a new file is introduced: ngpixis.c. Also update the P2020DS checkboard() function to use the new macros defined in the header file.
