* 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.

* MLK-10774-1 imx: LDO: add LDO bypassPeng Fan2015-04-29-0/+142
| | | | | | | | | | | | | | | | | | | | | | | | This patch is from two commits: 1. 748eac71fde78aa0c2e8cb3a3bab94bd994c06f5 ENGR00315499-5: Support i.MX6 1.2GHz via LDO bypass Add check for 1.2GHz core speed. If Speed grading fuse is for 1.2GHz, enable LDO bypass and setup PMIC voltages. LDO bypass is dependent on the flatten device tree file. 2. 93d457e4c601ee5266bc30b7dfa5fa1bbfa8500a MLK-9891-1: ARM: imx6: split WDOG_B setting from set_anatop_bypass() function We set WDOG_B in set_anatop_bypass() before, because it is the only case, but now on i.mx6sabreauto board, we didn't use ldo-bypass mode, but have to use WDOG_B to reboot whole board, so split these code to independent function so that board file can call it freely. Board code is not included, board ldo bypass code will be in bsp update code. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Moreover the MX6 SoC variant (Q, D, DL, S, SL) selection is currently done via the SYS_EXTRA_OPTIONS option which marked as deprecated. Move to a more standard way to select sub-architecture and board by creating a Kconfig under arch/arm/cpu/armv7/mx6 and a new ARCH_MX6 option. Existing MX6 board definitions should be moved in this new Kconfig in choice menu, and new boards should be directly declared in this menu.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: HYP/non-sec: relocation before enable secondary coresPeng Fan2015-03-01-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CONFIG_ARMV7_PSCI is not defined and CONFIG_ARMV7_SECURE_BASE is defined, smp_kicl_all_cpus may enable secondary cores and runs into secure_ram_addr( _smp_pen), before code is relocated to secure ram. So need relocation to secure ram before enable secondary cores. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Acked-by: Marc Zyngier <marc.zyngier@arm.com>
* | | | ARM: PSCI: Rework the DT handler slightlyTom Rini2015-03-09-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way the PSCI DT update happens currently means we pull in <asm/armv7.h> everywhere, including on ARMv8 and that in turn brings in <asm/io.h> for some non-PSCI related things that header needs to deal with. To fix this, we rework the hook slightly. A good portion of arch/arm/cpu/armv7/virt-dt.c is common looking and I hope that when PSCI is needed on ARMv8 we can re-use this by and large. So rename the current hook to psci_update_dt(), move the prototype to <asm/psci.h> and add an #ifdef that will make re-use later easier.

* | | | omap: gpmc: 'nandecc sw' can use HAM1 or BCH8Ash Charles2015-03-05-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'nandecc sw' command selects a software-based error correction algorithm. By default, this is OMAP_ECC_HAM1_CODE_SW but some platforms use OMAP_ECC_BCH8_CODE_HW_DETECTION_SW as their software-based correction algorithm. Allow a user to be specific e.g. # nandecc sw <hamming|bch8> where 'hamming' is still the default. Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set to a hardware-based ECC scheme---a little strange when the user has requested 'sw' ECC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The self-bias circuit is used by the bandgap during startup. Once the bandgap has stabilized, the self-bias circuit should be disabled for best noise performance of analog blocks. Also this bit should be disabled before the chip enters STOP mode or when ever the regular bandgap is disabled.

* | | | ti: armv7: Move SPL SDRAM init to the right place, drop unused CONFIG_SPL_STACKSimon Glass2015-03-04-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently in some cases SDRAM init requires global_data to be available and soon this will not be available prior to board_init_f(). Adjust the code paths in these cases to be correct. In some cases we had the SPL stack be in DDR as we might have large stacks (due to Falcon Mode + Environment). In these cases switch to CONFIG_SPL_STACK_R. In other cases we had simply been setting CONFIG_SPL_STACK into SRAM. In these cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also in SRAM) so drop those lines.

* | | | arm: Reduce the scope of lowlevel_init()Simon Glass2015-03-04-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function has grown into something of a monster. Some boards are setting up a console and DRAM here in SPL. This requires global_data which should be set up in one place (crt0.S). There is no need for SPL to use s_init() for anything since board_init_f() is called immediately afterwards.
