| * ppc/85xx: Use CONFIG_NS16550_MIN_FUNCTIONS to reduce NAND_SPL sizeKumar Gala2010-04-07-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC8536DS_NAND SPL build was failing due to code size increase introduced by commit: commit 33f57bd553edf29dffef5a6c7d76e169c79a6049 Author: Kumar Gala <galak@kernel.crashing.org> Date: Fri Mar 26 15:14:43 2010 -0500 85xx: Fix enabling of L1 cache parity on secondary cores We built in some NS16550 functions that we dont need and can get rid of them via CONFIG_NS16550_MIN_FUNCTIONS.

| * p2020ds: add alternate boot bank support using the ngPIXIS FPGATimur Tabi2010-04-07-89/+222
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * fsl: improve the PIXIS code and fix a few bugsTimur Tabi2010-04-07-170/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * ppc/8xxx: Delete PCI nodes from device tree if not configuredKumar Gala2010-04-07-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | If the PCI controller wasn't configured or enabled delete from the device tree (include its alias). For the case that we didn't even configure u-boot with knowledge of the controller we can use the fact that the pci_controller pointer is NULL to delete the node in the device tree. We determine that a controller was not setup (because of HW config) based on the fact that cfg_addr wasn't setup. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous code was failing when reading back the timer less than 400us after resetting it. This lead nand operations to incorrectly timeout any now and then. Moreover, writing the load register isn't immediately reflected in the value register. We must wait for a clock edge, so read_timer now waits for the value to change at least once, otherwise nand operation would timeout anyways (though less frequently).

* | nios2: Reload timer count in reset_timer()Scott McNutt2010-04-02-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the timestamp is incremented via interrupt and the interrupt period is greater than 1 msec, successive calls to get_timer() can produce inaccurate timing since the interrupts are asynchronous to the timing loop. For example, with an interrupt period of 10 msec two successive calls to get_timer() could indicate an elapsed time of 10 msec after only several hundred usecs -- depending on when the next interrupt actually occurs. This behavior can cause reliability issues with components such as CFI and NAND. This can be remedied by calling reset_timer() prior to establishing the base timestamp with get_timer(0), provided reset_timer() resets the hardware timer (rather than simply resetting only the timestamp). This has the effect of synchronizing the interrupts (and the advance of the timestamp) with the timing loop. Signed-off-by: Scott McNutt <smcnutt@psyent.com>
