* arm: ls102xa: workaround for cache coherency problemchenhui zhao2015-02-24-0/+28
| | | | | | | | | | The RCPM FSM may not be reset after power-on, for example, in the cases of cold boot and wakeup from deep sleep. It causes cache coherency problem and may block deep sleep. Therefore, reset them if they are not be reset. Signed-off-by: Chenhui Zhao <chenhui.zhao@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* arm/ls102xa: create TLB to map PCIe regionMinghuan Lian2015-02-24-10/+193
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LS1021A's PCIe1 region begins 0x40_00000000; PCIe2 begins 0x48_00000000. In order to access PCIe device, we must create TLB to map the 40bit physical address to 32bit virtual address. This patch will enable MMU after DDR is available and creates MMU table in DRAM to map all 4G space; then, re-use the reserved space to map PCIe region. The following the mapping layout. VA mapping: ------- <---- 0GB | | | | |-------| <---- 0x24000000 |///////| ===> 192MB VA map for PCIe1 with offset 0x40_0000_0000 |-------| <---- 0x300000000 | | |-------| <---- 0x34000000 |///////| ===> 192MB VA map for PCIe2 with offset 0x48_0000_0000 |-------| <---- 0x40000000 | | |-------| <---- 0x80000000 DDR0 space start |\\\\\\\| |\\\\\\\| ===> 2GB VA map for 2GB DDR0 Memory space |\\\\\\\| ------- <---- 4GB DDR0 space end Signed-off-by: Minghuan Lian <Minghuan.Lian@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

* ls102xa: fdt: Disable QSPI and DSPI in NOR/NAND/SD bootAlison Wang2015-01-23-0/+13
| | | | | | | | | | As QSPI/DSPI and IFC are pin multiplexed, QSPI and DSPI are only enabled in QSPI boot, and disabled in other boot modes. IFC is enabled in NOR/NAND/SD boot, and disabled in QSPI boot. This patch will add fdt support for the above rules.

* ls1021a: adding a secondary core boot address and kick functionsXiubo Li2014-12-11-0/+18
| | | | | | | | | | | | | | | Define the board specific smp_set_cpu_boot_addr() function to set the start address for secondary cores in the LS1021A specific manner. Define the board specific smp_kick_all_cpus() functioin to boot a secondary core. Here the BRR contains control bits for enabling boot for each core. On exiting HRESET or PORESET, the RCW BOOT_HO field optionally allows for logical core 0 to be released for booting or to remain in boot holdoff. All other cores remain in boot holdoff until their corresponding bit is set. Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
