2016-01-08pci: layerscape: Adjust the return value when ls_pcie_addr_valid() failsBin Meng
When trying to access non-existent/unsupported PCI devices in ls_pcie_read_config(), when ls_pcie_addr_valid() fails it returns error code and fills in the result with 0xffffffff manually. But it really should return zero to upper layer codes. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
2015-11-30pci/layerscape: add support for LS1043A PCIe LUT register accessMingkai Hu
The endian and base address of PEX LUT register region is different between Chassis 2 and Chassis 3, so move the base address definition to chassis specific header file and add pex_lut_* functions to access LUT register.

LS2080A is a prime personality of Freescale’s LS2085A. It is a non-AIOP personality without support of DP-DDR, L2 switch, 1588, PCIe endpoint etc. So renaming existing LS2085A code base to reflect LS2080A (Prime personality) Signed-off-by: Pratiyush Mohan Srivastava <pratiyush.srivastava@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> [York Sun: Dropped #ifdef in cpu.c for cpu_type_list] Reviewed-by: York Sun <yorksun@freescale.com>
2015-10-29armv8/fsl_lsch3: Change arch to fsl-layerscapeMingkai Hu
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.

2015-04-21pci/layerscape: fix link and class issues to support ls2085aMinghuan Lian
1. LS2085a provides PCIE_LUT_DBG register rather than PCIE_LDBG to show the link status, so the patch fixes it. 2. Increase the delay time to make sure that link training has finished. 3. Return invalid value when accessing multi-function device 4. For LS2085a DBI_RO_WR_EN bit is cleared as default, so we must set this bit before change DBI register value.
