* mx28evk: Provide default values for SPI bus and chip selectFabio Estevam2012-03-27-0/+2
| | | | | | | | | | Provide default values for SPI bus and chip select. This allows the command "sf probe" to work without passing SPI bus and chip select numbers as arguments. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Marek Vasut <marex@denx.de>

* mx6: Read silicon revision from registerFabio Estevam2012-03-27-3/+171
| | | | | | | | | | | | | | | Instead of hardcoding the mx6 silicon revision, read it in run-time. Also, besides the silicon version print the mx6 variant type: quad,dual/solo or solo-lite. Tested on a mx6qsabrelite, where it shows: CPU: Freescale i.MX6Q rev1.0 at 792 MHz Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de> Acked-by: Jason Liu <r64343@freescale.com>

| | | | | | | | | | | | | Cut down the VDDIO/VDDA regulator stabilization delays to 500 uS. That should be enough according to the datasheet and bootlets.

* mx6: Fix reset cause for Power On Reset caseFabio Estevam2012-03-27-0/+1
| | | | | | | | | | | | | After booting mx6qsabrelite from POR the following is reported: CPU: Freescale i.MX61 family rev1.0 at 792 MHz Reset cause: unknown reset This is because both the POR and WDOG bits are set after reset. Fix this by also checking both bits in the POR case. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

* i.MX6: mx6q_sabrelite: add CONFIG_REVISION_TAGEric Nelson2012-03-27-0/+6
| | | | | | | | | | | | | | This is needed to support Freescale-supplied userspaces. At the moment, both the IPU and VPU libraries provided by Freescale in the "imx-lib" package contain routines which scrape the system revision from /proc/cpuinfo. In the VPU library, this information is used to load the proper firmware, allowing a single binary to be used across various i.MX processors.

* imximage: Remove overwriting of flash_offsetDirk Behme2012-03-27-4/+15
| | | | | | | | | | | | | | | | | | | | The flash header supports different flash offsets for different boot devices. E.g. parallel NOR or OneNAND use a different offset than FLASH_OFFSET_STANDARD (== 0x400). The flash offset is correctly read from the configuration in parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2(). Fix this by removing this overwriting. Use the flash offset correctly read from the configuration, instead. If there is no flash_offset read from the configuration file, i.e. the BOOT_FROM tag is missing, exit with an error message.
