* ENGR00320350 iMX6SLEVK: Fix build warning of PCIE Phy power downYe.Li2015-04-29-0/+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> (cherry picked from commit 987c48c07c9ef62fa3fe55faa6f7369b30637127) Signed-off-by: Peng Fan <Peng.Fan@freescale.com>

* ENGR00319415 pcie: random link down issue after warm-rstRichard Zhu2015-04-29-0/+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.

* MLK-10774-3 iMX6SX/SL: Modify SOC to support two ENETPeng Fan2015-04-29-3/+40
| | | | | | | | | | | | | | | | | | | 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. 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. 2. Modify the MAC address function "imx_get_mac_from_fuse" to get either ENET MAC address. 3. Add configuration "CONFIG_FEC_MXC_25M_REF_CLK" to enable ENET 25Mhz reference clock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in fc46bae a "clean up" was introduced that intended to reconcile some of the AM335x codepaths based on how AM43xx operates. Unfortunately this introduced a regression on the DDR2 platforms. This was un-noticed on DDR3 (everything except for Beaglebone White) as we had already populated sdram_config correctly in sequence. This change brings us back to the older behavior and is fine on all platforms.

| * | Exynos5: Fix rpll_sdiv to support both peach-pit and peach-pi panelsAjay Kumar2015-04-06-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing setting for rpll_sdiv generates 70.5Mhz RPLL video clock to drive 1366x768 panel on peach_pit. This clock rate is not sufficient to drive 1920x1080 panel on peach-pi. So, we adjust rpll_sdiv to 3 so that it generates 141Mhz pixel clock which can drive peach-pi LCD. This change doesn't break peach-pit LCD since 141/2=70.5Mhz, i.e FIMD divider at IP level will get set to 1(the required divider setting will be calculated and set by exynos_fimd_set_clock()) and hence peach-pit LCD still works fine.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My main motivations for this commit are: [1] Follow the arch/arm/Makefile style of Linux Kernel [2] Maintain compiler options systematically Currently, we give -march=* and -mtune=* options inconsistently: Only some of the CPUs pass -march=* and -mtune=* options. By collecting such options into the single place arch/arm/Makefile we can tell which options are missing at a glance. [3] Prepare for deprecating arch/*/cpu/*/config.mk Note: This commit just moves the compiler options so as not to change the behavior at all. It does not care about the correctness of the given options. Fox example, "-march=armv5te" might be better than "-march=armv4" for ARM946EJS, but it is beyond the scope this commit. Also, filling the missing -march=* and -tune=* is left to follow-up patches.

* | | ARM: OMAP3: rx51: Enable workaround for ARM errata 454179, 430973, 621766Nishanth Menon2015-03-13-25/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RX51 has a secure logic which uses different parameters compared to traditional implementation. So, make the generic secure acr write over-ride-able by board file and refactor rx51 code to use this. While at it, enable the OMAP3 specific errata code for 454179, 430973, 621766.

* | | ARM: DRA7 / OMAP5: Add workaround for ARM errata 798870Praveen Rao2015-03-13-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the workaround for ARM errata 798870 for OMAP5 / DRA7 which says "If back-to-back speculative cache line fills (fill A and fill B) are issued from the L1 data cache of a CPU to the L2 cache, the second request (fill B) is then cancelled, and the second request would have detected a hazard against a recent write or eviction (write B) to the same cache line as fill B then the L2 logic might deadlock." An l2auxctlr accessor implementation for OMAP5 and DRA7 is introduced here as well.

* | | ARM: OMAP: Change set_pl310_ctrl_reg to be genericNishanth Menon2015-03-13-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set_pl310_ctrl_reg does use the Secure Monitor Call (SMC) to setup PL310 control register, however, that is something that is generic enough to be used for OMAP5 generation of processors as well. The only difference being the service being invoked for the function. So, convert the service to a macro and use a generic name (same as that used in Linux for some consistency). While at that, also add a data barrier which is necessary as per recommendation. While at this, smc #0 is maintained as handcoded assembly thanks to various gcc version eccentricities, discussion thread: http://marc.info/?t=142542166800001&r=1&w=2 Signed-off-by: Nishanth Menon <nm@ti.com> Tested-by: Matt Porter <mporter@konsulko.com> Reviewed-by: Tom Rini <trini@konsulko.com>
