* ENGR00321260-1 iMX6: Add support to get CPU serial numberYe.Li2014-07-04-0/+13
| | | | | | | | The android boot needs get_board_serial function to get the CPU uid as the serial number. Implement this function to read the uid from fuse for all iMX6 platforms. Signed-off-by: Ye.Li <B37916@freescale.com>
* ENGR00320350 iMX6SLEVK: Fix build warning of PCIE Phy power downYe.Li2014-06-30-0/+2
| | | | | | | | | | | | Since the iMX6SL does not have PCIE module, should not define the function "imx_set_pcie_phy_power_down" for it. Otherwise, get the build warning below: arch/arm/cpu/armv7/mx6/soc.c:446:13: warning: 'imx_set_pcie_phy_power_down' defined but not used [-Wunused-function] static void imx_set_pcie_phy_power_down(void) Signed-off-by: Ye.Li <B37916@freescale.com>

* ENGR00319415 pcie: random link down issue after warm-rstRichard Zhu2014-06-24-0/+18
| | | | | | | | | | | | | | | | | There are about 0.02% percentage on some imx6q/dl/solo hw boards, random pcie link down when warm-reset is used. Make sure to clear the ref_ssp_en bit16 of gpr1 before warm-rst, and set ref_ssp_en after the pcie clks are stable to workaround it. rootcause: * gpr regisers wouldn't be reset by warm-rst, while the ref_ssp_en is required to be reset by pcie. (work-around in u-boot) * ref_ssp_en should be set after pcie clks are stable. (work-around in kernel) Signed-off-by: Richard Zhu <r65037@freescale.com>

* ENGR00315894-54 iMX6SX/SL: Modify SOC to support two ENETYe.Li2014-06-17-4/+64
| | | | | | | | | | | | | | | | | | | | | iMX6SX has different enet system clocks with iMX6SL, and has two ENET controllers. So update clocks and soc APIs accordingly to support this features. 1. Modify the clock API "enable_enet_clock" to enable enet system clock for enet controllers. 2. Enet RGMII TX clock source may come from external or internal PLL. By default, use the external phy CLK_25M output as TX clock source. When using internal PLL as source, the function enable_fec_anatop_clock must be called to enable clock for each enet controller. 3. Modify the MAC address function "imx_get_mac_from_fuse" to get either ENET MAC address. 4. Add configuration "CONFIG_FEC_MXC_25M_REF_CLK" to enable ENET 25Mhz reference clock. 5. Modify imx6slevk BSP to fit the new APIs. Signed-off-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Ye.Li <B37916@freescale.com>

To enable low freq boot mode, need to set BOOT_CFG2[2] to high, tested on i.MX6Q/DL SabreSD board and i.MX6SL EVK board.

The SATA clock enabling function starts up the 100MHz SATA reference PLL in ENET_PLL register, but the code can be re-used to enable the 125MHz PCIe reference in ENET_PLL, so pull this code into separate function.
