* pci: minor cleanup of CONFIG_PCI_PNP usageAndrew Sharp2012-09-02-6/+6
| | | | | | | | | Refactor the common PCI code just a tiny bit surrounding the PCI_PNP (pciauto) stuff. Makes the code a tiny bit easier to read, and also makes it more obvious that almost no platform needs to setup or use the pci_config_table stuff. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>
* pci: clean up some whitespace and formattingAndrew Sharp2012-09-02-70/+91
| | | | | | | | | | | I tried to clean up the white space and formatting offenses and inconsistencies in the generic PCI code that obviously has been around for some time. Emphasis on large increases in readability and maintainability and consistency. I omitted the platform/processor specific files in the drivers/pci directory because I wanted to leave those file to those that care more about them. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>

| * config: Always use GNU ldKhem Raj2012-08-10-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes sure that we always use the GNU ld. U-Boot uses certain construct e.g. OVERLAY which are not implemented in gold therefore it always needs GNU ld for linking. It works well if default linker in toolchain is GNU ld but in some cases we can have gold to be the default linker and also ship GNU ld but not as default in such cases its called $(PREFIX)ld.bfd, with this patch we make sure that if $(PREFIX)ld.bfd exists than we use that for our ld. This way it does not matter what the default ld is. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Signed-off-by: Khem Raj <raj.khem@gmail.com> Acked-by: Mike Frysinger <vapier@gentoo.org>

* | at91: atmel_nand: Update driver to support Programmable Multibit ECC controllerWu, Josh2012-09-01-1/+836
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Programmable Multibit ECC (PMECC) controller is a programmable binary BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller can be used to support both SLC and MLC NAND Flash devices. It supports to generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data. To use PMECC in this driver, the user needs to set the PMECC correction capability, the sector size and ROM lookup table offsets in board config file. This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference is in this version it uses registers structure access hardware instead of using macros. It is tested in 9x5 serial boards. Signed-off-by: Josh Wu <josh.wu@atmel.com> [rebase] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

This avoids setting no_snoop for all i.MX boards, and it prevents setting a reserved bit of a reserved register if fsl_esdhc_mmc_init() is used on i.MX, like in arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | production U-Boot We have no idea where the DCD was derived from for Smartbook support, but they differ from the Smarttop settings, MX51EVK settings and certainly don't correspond to any shipped or development version of U-Boot that Genesi has ever had on any Smartbook. So, copy the calibrated, verified settings from the U-Boot as shipped with every Smartbook since retail production. Remove those few settings that just set the POR defaults which have already been confirmed for the previous Smarttop DCD change. One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks basically don't exist at retail and the number of units in the world is less than 5 (3 of which are at the Genesi office or owned by Genesi employees). Many hours of memory testing confirms the new settings are stable.

It should never have been set to 1.2V even on i.MX51 TO2 and all available Linux kernels would drop the voltage to 1.1V anyway and work reliably.

* | efikamx: configure Smarttop PCBID and LED pads in DCD for convenienceMatt Sealey2012-09-01-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCBID pads seem to need time to settle due to external pulldowns, otherwise we are reading floating GPIO pins with implicit pad pullups and get the wrong data. However we can't "wait" at the time we need them before relocation, since timers are not available. The time taken to get from DCD to the code requiring the pads set seems to be more than long enough (even with caches enabled). We have space in the DCD due to the DDR settings changes to configure all the pad settings we need for this, plus the LED pad settings too which reduces the amount of code required later on.

* | efikamx: remove drive strength function and roll its functionality into the DCDMatt Sealey2012-09-01-101/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Efika MX boards configure their DDR pad settings twice, one in the DCD generated from imximage_*.cfg and again in init_drive_strength called before relocation. Rather than doing this, roll the changes it makes into the DCD so DDR is set up before a single line of code in U-Boot is run. The settings are identical with this DCD block which is shorter (by 7 entries) than the old one, and after the output of init_drive_strength since a lot of the functionality in the existing DCD and init_drive_strength function was just setting the POR defaults. This goes to explain some now-missing entries. Several hundred rounds of mtest have been run to test the settings before and after to confirm DDR is stable and no ill-effects have been found.
