* armv8/fsl_lsch3: Change arch to fsl-layerscapeMingkai Hu2015-10-291-355/+0
| | | | | | | | | | | | | There are two LS series processors are built on ARMv8 Layersacpe architecture currently, LS2085A and LS1043A. They are based on ARMv8 core although use different chassis, so create fsl-layerscape to refactor the common code for the LS series processors which also paves the way for adding LS1043A platform.

* armv8: Add framework for CCN-504 interconnect configurationBhupesh Sharma2015-09-011-7/+65
| | | | | | | | | | | | This patch adds a minimal framework for Dickens CCN-504 interconnect configuration - mainly related to adding Clusters/cores to snoop/DVM domain and setting QoS of the RN-I ports. LS2085A platform makes use of these configurations to support better network data performance and to boot a SMP Linux.

* armv8/ls2085a: Fix generic timer clock sourceYork Sun2015-04-231-0/+6
| | | | | | | | | | The timer clock is system clock divided by 4, not fixed 12MHz. This is common to the SoC, not board specific. Primary core is fixed when u-boot still runs in board_f. Secondary cores are fixed by reading a variable set by u-boot. Signed-off-by: York Sun <yorksun@freescale.com> CC: Mark Rutland <mark.rutland@arm.com>
* armv8/fsl-lsch3: Convert flushing L3 to assembly to avoid using stackYork Sun2015-02-241-0/+78
| | | | | | | | | | | | Flushing L3 cache in CCN-504 requries d-cache to be disabled. Using assembly function to guarantee stack is not used before flushing is completed. Timeout is needed for simualtor on which CCN-504 is not implemented. Return value can be checked for timeout situation. Change bootm.c to disable dcache instead of simply flushing, required by flushing L3. Signed-off-by: York Sun <yorksun@freescale.com>
* fsl-ch3/lowlevel: TZPC and TZASC programming to configure non-secure accessesBhupesh Sharma2015-02-241-0/+54
| | | | | | | | | | | | | This patch ensures that the TZPC (BP147) and TZASC-400 programming happens for LS2085A SoC only when the desired config flags are enabled and ensures that the TZPC programming is done to allow Non-secure (NS) + secure (S) transactions only for DCGF registers. The TZASC component is not present on LS2085A-Rev1, so the TZASC-400 config flag is turned OFF for now.

* armv8/fsl-lsch3: Release secondary cores from boot hold off with Boot PageYork Sun2014-09-251-20/+105
| | | | | | | | | | 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 FSL_LSCH3 SoCYork Sun2014-07-031-0/+65
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.
