* sunxi: fix 64-bit compiler warning for SPL header parsingAndre Przywara2016-09-06-1/+1
| | | | | | | | | | Casting "int"s to pointers is only valid for 32-bit systems. Add the appropriate pointer type cast to avoid a compiler warning when compiling for AArch64.

* sunxi: On newer SoCs use words 1-3 instead of just word 3 from the SIDHans de Goede2016-07-31-1/+19
| | | | | | | | | | | | | | | | It seems that bytes 13-14 of the SID / bytes 1-2 from word 3 of the SID are always 0 on H3 making it a poor candidate to use as source for the serialnr / mac-address, and the other non constant words (1 and 2) also have quite a few bits which are the same for some boards, This commits switches to using the crc32 of words 1 - 3 to get a more unique value for the mac-address / serialnr.

* sunxi: Ensure that the NIC specific bytes of the mac are not all 0Hans de Goede2016-07-31-0/+4
| | | | | | | | | | | | | | On 2 of my H3 boards bytes 13-15 of the SID are all 0 leading to the NIC specific bytes of the mac all being 0, which leads to the boards not getting an ipv6 address from the dhcp server. This commits adds a check to ensure this does not happen.

| | | | | | | | | | | | We always define CONFIG_MISC_INIT_R on sunxi and misc_init_r is never called in the spl, so the linker will optimize it and parse_spl_header(), of which it is the only caller, away.

* sunxi: Add support for multiple ethadrr-essesHans de Goede2016-07-15-16/+47
| | | | | | | | | | | | | | | | Currently we fill ethaddr with a fixed unique address based on the SoCs serial (from the sid) to make sure that boards which use the integrated emac / gmac get a fixed mac rather then a random one. On some boards the wifi does not come with a fixed mac either, so we need to also set eth1addr. This commit changes the ethaddr setting code to check for ethernet%d aliases (as fdt_fixup_ethernet does) and set an ethaddr variable for all present aliases.

* sunxi: FEL - Add the ability to recognize and auto-import uEnv-style dataBernhard Nortmann2016-07-15-8/+21
| | | | | | | | | | | | | | | | | | | | | | | | The patch converts one of the "reserved" fields in the sunxi SPL header to a fel_uEnv_length entry. When booting over USB ("FEL mode"), this enables the sunxi-fel utility to pass the string length of uEnv.txt compatible data; at the same time requesting that this data be imported into the U-Boot environment. If parse_spl_header() in the sunxi board.c encounters a non-zero value in this header field, it will therefore call himport_r() to merge the string (lines) passed via FEL into the default settings. Environment vars can be changed this way even before U-Boot will attempt to autoboot - specifically, this also allows overriding "bootcmd". With fel_script_addr set and a zero fel_uEnv_length, U-Boot is safe to assume that data in .scr format (a mkimage-type script) was passed at fel_script_addr, and will handle it using the existing mechanism ("bootcmd_fel").

* sunxi: Turn satapwr on from board_initHans de Goede2016-03-23-0/+4
| | | | | | | | | | | | | | | | | | There are 2 reasons for doing this: 1) The main reason for doing this is to move it outside of board/sunxi/ahci.c, so that it can be used on boards which use a usb<->sata chip too; 2) While doing this I realized that doing it from board_init also meant doing it much earlier. Some printf get_timer(0) calls show that the time between board_init() and scsi_init() is more then 600 ms, so we can drop the mdelay(500) While at it also drop the printf("SUNXI SCSI INIT\n") AHCI init is noisy enough by itself.

* sunxi: Fix gmac not working due to cpu_eth_init no longer being calledHans de Goede2016-03-23-0/+5
| | | | | | | | | | | | | | | | | | | | cpu_eth_init is no longer called for dm enabled eth drivers, this was causing the sunxi gmac eth controller to no longer work in u-boot. This commit fixes this by calling the clock, reset and pinmux setup function from s_init() and enabling the phy power pin (if any) from board_init(). The enabling of phy power cannot be done from s_init because it uses dm and dm is not ready yet at this point. Note that the mdelay is dropped as the phy gets enabled much earlier now, so it is no longer needed.

If found, and the loader ("fel" utility) provided a non-zero value for the boot.scr address, then the corresponding environment variable fel_scriptaddr gets set. misc_init_r() also sets (or clears) the "fel_booted" variable depending on the active boot device, using the same logic as spl_boot_device(). The goal is to provide sufficient information (within the U-Boot environment) to make intelligent decisions on how to continue the boot process, allowing specific customizations for the "FEL boot" case.

| | | | | | | | | | | | | | | | | | | The 2/3 usb-phys on the sunxi SoCs are really a single separate functional block, and are modelled as such in devicetree. So once we've moved all the sunxi usb code to the driver-model then phy_probe will be called once for the entire block from the driver-model enumeration code. Move to this now as this also avoids problems with phy_probe being called multiple times once we introduce ohci support. This also allows us to get rid of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed to be called only once. Since we're effectively rewriting the probe / remove functions, move them to the end of the file while we are at it, as that is the most logical place for them.

| | | | | | | | | | | Sunxi platforms come with at least 3 TWI (I2C) controllers and some platforms even have up to 5. This adds support for every controller on each supported platform, which is especially useful when using expansion ports on single-board- computers.

* sunxi: Complete mmc pin mux for each supported platform, configured with KconfigPaul Kocialkowski2015-04-15-5/+126
| | | | | | | | | | | | | Sunxi platforms have different possible mmc pin mux setups (except for mmc0), which are different across platforms. This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig options. This is especially relevant when a second (in addition to mmc0) port is used and CONFIG_MMC_SUNXI_SLOT_EXTRA is enabled.

* sunxi: GPIO pin mux hardware-feature-specific function index definesPaul Kocialkowski2015-04-15-6/+6
| | | | | | | | | | | Each hardware feature exposed through the GPIO pin mux is usually using the same function index (for a given port), so there is no need to define one value per pin: one value per hardware feature per port is sufficient, avoids duplication and makes everything easier to understand.
