* mx53ard: Initialize return code with errorFabio Estevam2012-03-27-1/+1
| | | | | | | | | The variable "rc" is the return of board_eth_init() function. Initialize it with an error code, so that this function can return an error when CONFIG_SMC911X is not set. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de>
* mx53: Make PLL2 to be the parent of UART clockFabio Estevam2012-03-27-3/+17
| | | | | | | | | | | | | | | | | | Change the parent UART clock to be PLL2, so that U-boot can also boot a Freescale 2.6.35 kernel for mx53. FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid conflicts with IPU clocks, so that the video resolution can be changed without affecting the UART clock. On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded and this patch fixes this problem. Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.

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.

* 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.
