arm: ls1021a: Ensure LS1021 ARM Generic Timer CompareValue Set 64-bit

2015-11-30T16:53:01Z

This patch addresses a problem mentioned recently on this mailing list: [1]. In that posting a LS1021 based system was locking up at about 5 minutes after boot, but the problem was mysteriously related to the toolchain used for building u-boot. Debugging the problem reveals a stuck interrupt 29 on the GIC. It appears Freescale's LS1021 support in u-boot erroneously sets the 64-bit ARM generic PL1 physical time CompareValue register to all-ones with a 32-bit value. This causes the timer compare to fire 344 seconds after u-boot configures it. Depending on how fast u-boot gets the kernel booted, this amounts to about 5-minutes of Linux uptime before locking up. Apparently the bug is masked by some toolchains. Perhaps this is explained by default compiler options, word sizes, or binutils versions. At any rate this patch makes the manipulation explicitly 64-bit which alleviates the issue.

arm/ls102xa:add hwconfig setting to support disable unused devices

2015-09-02T02:49:20Z

DEVDISRn registers provides a mechanism for gating clocks of IP blocks that are not used. Here we implement hwconfig option to allow users to disable unused peripherals on the board. For ex. If eSDHC/qDMA/eDMA are unused and with disabled status in dts, User can enable CONFIG_FSL_DEVICE_DISABLE and set "devdis:esdhc,qdma,edma" in hwconfig, thus ESDHC controller & eDMA/qDMA will be clock gated to save more power.

2015-09-02T02:39:03Z

Replace the DMACTRL[LE] hack with recommended settings for ETSECDMAMCR to get the same end effect - obtaining big-endian buffer descriptors and frame data for eTSEC. The reset / default value for ETSECDMAMCR is preserved, excepting the BD and FR bits which are cleared to enable the BE mode in accordance with the H/W specifications.
