2010-07-16ppc/85xx: Add a structure defn for PIXIS registersKumar Gala
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.

2010-04-07fsl: improve the PIXIS code and fix a few bugsTimur Tabi
Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx boards. This makes the code easier to read and more flexible. Delete pixis.h, because none of the exported functions were actually being used by any other file. Make all of the functions in pixis.c 'static'. Remove "#include pixis.h" from every file that has it. Remove some unnecessary #includes. Make 'pixis_base' into a macro, so that we don't need to define it in every function. Add "while(1);" loops at the end of functions that reset the board, so that execution doesn't continue while the reset is in progress. Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where appropriate. Replace ulong/uint with their spelled-out equivalents. Remove unnecessary typecasts, changing the types of some variables if necessary. Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make it easier for specific boards to support variations in the PIXIS registers sets. No current boards appears to need this feature. Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD. Apparently, "pixis_reset altbank" has never worked on this board.

2007-04-09Add PIXIS FPGA support for MPC8641HPCN board.Haiying Wang
Move the 8641HPCN's PIXIS code to the new directory board/freescale/common/ as it will be shared by future boards not in the same processor family. Write a "pixis_reset" command that utilizes the FPGA reset sequencer to support alternate soft-reset options such as using the "alternate" flash bank, enabling the watch dog, or choosing different CPU frequencies. Add documentation for the pixis_reset to README.mpc8641hpcn. Signed-off-by: Haiying Wang <haiying.wang@freescale.com> Signed-off-by: Jon Loeliger <jdl@freescale.com>
