| | | | | | | | | The base addresses used in at91sam926x_board_init() differ with each SoC. The board knows which SoC we are running on though, so create and use SoC specific variants of these functions which pass the appropriate base addresses to at91sam926x_board_init().

| | | | | | | | The pmc accessor function depends on a compile time base address, so rather use writel directly. In this case we can hardcode the base address again since all at91sam926x SoCs have the same pmc base address. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | The aim with this conversion is to drop the dependency where the mach-at91/ code call code in the boards file. This dependency must be dropepd to enable multi-image builds. The selection of lowlevel_init functions are pushed to the individual boards. Use AT91SAM926X_BOARD_INIT for the boards that share the at91sam926x_board_init file, and push this to the individual boards. To be used in follow-up patches bootstrap is likewise pushed out to the individual boards.

* at91sam9x5: fix ROM base address (bugfix for nand ECC)iEdoardo Scaglia2015-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The ROM base address in the 9x5 processors lives at 1M, not 4M, where SMD is, as defined later in the same file. The ROM includes some tables that are used to build error-correction data for NAND memory. By using the wrong address, we get wrong data and the result is undetected bit flips (data at 0x408000 is all zeroes). Thus, even though our kernel was fixing bit errors in NAND, barebox was not fixing them. With UBI (our situation) we got I/O errors because the checksum verification for data nodes failed. Using the proper address corrects the problem: barebox reports a "bitflip" message, consistent with the kernel message for the same file, and the files are properly loaded and booted. Note: the kernel has the same wrong define, but then the magic number 0x00108000 as spelled in arch/arm/boot/dts/at91sam9x5.dtsi is used instead of the symbolic name.
