* armv8/fsl-lsch3: Change normal memory shareabilityYork Sun2015-02-241-3/+3
| | | | | | | According to hardware implementation, a single outer shareable global coherence group is defined. Inner shareable has not bee enabled. Signed-off-by: York Sun <yorksun@freescale.com>
* armv8/fsl-lsch3: Release secondary cores from boot hold off with Boot PageYork Sun2014-09-251-0/+13
| | | | | | | | | | Secondary cores need to be released from holdoff by boot release registers. With GPP bootrom, they can boot from main memory directly. Individual spin table is used for each core. Spin table and the boot page is reserved in device tree so OS won't overwrite. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Arnab Basu <arnab.basu@freescale.com>
* armv8/fsl-lsch3: Add support to load and start MC FirmwareJ. German Rivera2014-07-031-0/+11
| | | | | | | | | | | | | | | | Adding support to load and start the Layerscape Management Complex (MC) firmware. First, the MC GCR register is set to 0 to reset all cores. MC firmware and DPL images are copied from their location in NOR flash to DDR. MC registers are updated with the location of these images. Deasserting the reset bit of MC GCR register releases core 0 to run. Core 1 will be released by MC firmware. Stop bits are not touched for this step. U-boot waits for MC until it boots up. In case of a failure, device tree is updated accordingly. The MC firmware image uses FIT format. Signed-off-by: J.

* ARMv8/FSL_LSCH3: Add FSL_LSCH3 SoCYork Sun2014-07-031-0/+425
Freescale LayerScape with Chassis Generation 3 is a set of SoCs with ARMv8 cores and 3rd generation of Chassis. We use different MMU setup to support memory map and cache attribute for these SoCs. MMU and cache are enabled very early to bootst performance, especially for early development on emulators. After u-boot relocates to DDR, a new MMU table with QBMan cache access is created in DDR. SMMU pagesize is set in SMMU_sACR register. Both DDR3 and DDR4 are supported.
