* mx6: Fix use of improper value in enable_ipu_clockPierre Aubert2013-09-27-1/+1
| | | | | | | | | The value MXC_CCM_CCGR3_IPU1_IPU_DI0_OFFSET that was used to initialize the CCGR3 register caused an undefined value for CG0. Signed-off-by: Pierre Aubert <p.aubert@staubli.com> CC: Stefano Babic <sbabic@denx.de> Acked-by: Eric Nelson <eric.nelson@boundarydevices.com>

* mx6: Fix calculation of emi_slow clock rateAndrew Gabbasov2013-09-10-4/+4
| | | | | | | | | | | | | This is porting of Freescale's patch from version imx_v2009.08_3.0.35_4.0.0, that fixes the obvious mistype of bits offset macro name (ACLK_EMI_PODF_OFFSET was used instead of ACLK_EMI_SLOW_PODF_OFFSET). Using the occasion, change the variable name 'emi_slow_pof' to more consistent 'emi_slow_podf'.

* mx6: Fix get_board_rev() for the mx6 solo caseFabio Estevam2013-04-03-0/+12
| | | | | | | | | | | | | | | | | | When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev() returns 0x62xxx, which is not a value understood by the VPU (Video Processing Unit) library in the kernel and causes the video playback to fail. The expected values for get_board_rev are: 0x63xxx: For mx6quad/dual 0x61xxx: For mx6dual-lite/solo So adjust get_board_rev() accordingly and make it as weak function, so that we do not need to define it in every mx6 board file.

* mx6: Disable Power Down Bit of watchdogFabio Estevam2013-02-12-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a mx6qsabresd revision C board with rev1.2 mx6q, the system gets resetted and it is not able to reach the Linux prompt. Comparing the watchdog behaviour on a revB versus revC board: - On a mx6qsabresd revB: U-Boot > reset resetting ... U-Boot 2013.01-10524-g432a3aa-dirty (Feb 07 2013 - 13:34:46) CPU: Freescale i.MX6Q rev1.1 at 792 MHz Reset cause: WDOG ... - On a mx6qsabresd revC: U-Boot > reset resetting ... U-Boot 2013.01-10524-g432a3aa-dirty (Feb 07 2013 - 13:34:46) CPU: Freescale i.MX6Q rev1.1 at 792 MHz Reset cause: POR So due to revC POR/watchdog circuitry whenever a watchdog occurs, it causes a POR. Clearing the PDE - Power Down Enable bit of WMCR registers fixes the problem and is also safe for all mx6 boards.

* mx6: Add workaround for ARM errataFabio Estevam2013-01-09-0/+10
| | | | | | | | | | | | | | | | | | Add workaround for the following ARM errata: 743622 and 751472. The motivation for this change is the following kernel commit 62e4d357a (ARM: 7609/1: disable errata work-arounds which access secure registers), which removes the errata from multiplatform kernel. Since imx has been converted to multiplatform in the kernel, we need to apply such workarounds into the bootloader. Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel. Explanation of each erratum is provided at "Chip Errata for the i.MX 6Dual/6Quad" document available at: cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
