* x86: Probe pinctrl driver in cpu_init_r()Bin Meng2016-06-122-7/+5
| | | | | | | | | | | | | | | | | | | | | | At present pinctrl driver gets probed in ich6_gpio driver's probe routine, which has two issues: - Pin's PADs only gets configured when GPIO driver is probed, which is not done by default. This leaves the board in a partially functional state as we must initialize PADs correctly to get perepherals fully working. - The probe routine of pinctrl driver is called multiple times, as normally there are multiple GPIO controllers. It should really be called just once. Move the call to syscon_get_by_driver_data() from ich6_gpio driver to cpu_init_r().

* x86: baytrail: Configure card detect pin of the SD controllerBin Meng2016-06-123-0/+45
| | | | | | | | | | | | | | | | | | | | | As of today, the latest version FSP (gold4) for BayTrail misses the PAD configuration of the SD controller's Card Detect signal. The default PAD value for the CD pin sets the pin to work in GPIO mode, which causes card detect status cannot be reflected by the Present State register in the SD controller (bit 16 & bit 18 are always zero). Add a configuration for this pin in the pinctrl node. Note I've checked the PAD configuration for all the pins in all the 3 controllers (eMMC/SDIO/SD). Only this SDMMC3_CD_B pin does not get initialized to correct mode by FSP. With fsp,emmc-boot-mode set to 2 (eMMC 4.1), eMMC pins are initialized to func 1, but if we set fsp,emmc-boot-mode to 1 (auto), those pins are initialized to func 3 which is correct according to datasheet.

* x86: baytrail: Change fsp, emmc-boot-mode to "auto"Bin Meng2016-06-123-3/+3
| | | | | | | | | | | | | | | | | | At present all BayTrail boards configure fsp,emmc-boot-mode to 2, which means "eMMC 4.1" per FSP documentation. However, eMMC 4.1 only shows up on some early stepping silicon of BayTrail SoC. Newer stepping SoC integrates an eMMC 4.5 controller. Intel FSP provides a config option fsp,emmc-boot-mode which tells FSP which eMMC controller it initializes. Instead of hardcoded to 2, now we change it to 1 which means "auto". With this change, MinnowMax board (with a D0 stepping BayTrail SoC) can see the eMMC 4.5 controller at PCI address 00.17.00 via U-Boot 'pci' command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The exynos5 platforms use DM in U-Boot and do not use DM in SPL. The serial driver, serial_s5p.c, is DM-only. This is OK for U-Boot, but in SPL, this will fail with the following compile error: drivers/built-in.o: In function `get_current': ...u-boot/drivers/serial/serial.c:387: undefined reference to `default_serial_console' This warning happens because common/console.c is compiled into U-Boot SPL if CONFIG_SPL_SERIAL_SUPPORT . The common/console.c invokes serial_*() functions and since exynos5 does not use DM in SPL, these functions come from drivers/serial/serial.c . The serial_*() locate default serial port by calling default_serial_console(), but because the serial_s5p.c is DM-only, it does no longer define default_serial_console(). Thus the error.
