* rockchip: clk: Make rkclk_get_clk() SoC-specificSimon Glass2016-01-21-29/+0
| | | | | | | | | | | | The current method assumes that clocks are numbered from 0 and we can determine a clock by its number. It is safer to use an ID in the clock's platform data to avoid the situation where another clock is bound before the one we expect. Move the existing code into rk3036 since it still works there. Add a new implementation for rk3288. Signed-off-by: Simon Glass <sjg@chromium.org>

The relevant bits have been extracted from the 'synogpl-5004-armadaxp' package Synology kindly published, garnished with a fair amount of trial-and-error. Sadly, support is far from perfect. The major parts I have failed in are SATA and XHCI support. Details about these and some other things follow: Device Tree ----------- The device tree file armada-xp-synology-ds414.dts has been copied from Linux and enhanced by recent U-Boot specific changes to armada-xp-gp.dts. SATA Support ------------ There is a Marvell 88SX7042 controller attached to PCIe which is supported by Linux's sata_mv driver but sadly not U-Boot's sata_mv. I'm not sure if extending the latter to support PCI devices is worth the effort at all. Porting sata_mv from Linux exceeded my brain's capacities. :( XHCI Support ------------ There is an EtronTech EJ168A XHCI controller attached to PCIe which drives the two rear USB3 ports. After a bit of playing around I managed to get it recognized by xhci-pci, but never was able to access any devices attached to it. Enabling it in ds414 board config shows that it does not respond to commands for whatever reason. The (somewhat) bright side to it is that it is not even supported in Synology's customized U-Boot, but that also means nowhere to steal the relevant bits from. EHCI Support ------------ This seems functional after issuing 'usb start'. At least it detects USB storage devices, and IIRC reading from them was OK. OTOH Linux fails to register the controller if 'usb start' wasn't given before in U-Boot. According to Synology sources, this board seems to support USB device (gadget?) mode. Though I didn't play around with it. PCIe Support ------------ This is fine, but trying to gate the clocks of unused lanes will hang PCI enum. In addition to that, pci_mvebu seems not to support DM_PCI. DDR3 Training ------------- Marvell/Synology uses eight PUPs instead of four. Does not look like this is meant to be customized in mainline U-Boot at all. OTOH I have no idea what a "PUP" actually is. PEX Init -------- Synology uses different values than mainline U-Boot with this patch: pex_max_unit_get returns 2, pex_max_if_get returns 7 and max_serdes_lines is set to 7. Not changing this seems to not have an impact, although I'm not entirely sure it does not cause issues I am not aware of. Static Environment ------------------ This allows to boot stock Synology firmware at least. In order to be a little more flexible when it comes to booting custom kernels, do not only load zImage partition, but also rd.gz into memory. This way it is possible to use about 7MB for kernel with piggyback initramfs. Signed-off-by: Phil Sutter <phil@nwl.cc> Acked-by: Stefan Roese <sr@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Armada XP has support for X4 lanes, boards specify this in their serdes_cfg. During PEX init in high_speed_env_lib.c, the configuration is stored in GEN_PURP_RES_2_REG. When enumerating PEX, subsequent interfaces of an X4 lane must be skipped. Otherwise the enumeration hangs up the board. The way this is implemented here is not exactly beautiful, but it mimics how Marvell's BSP does it. Alternatively we could get the information using board_serdes_cfg_get(), but that won't lead to clean code, either.

| * arm: mvebu: Add runtime detection of UART (xmodem) boot-modeStefan Roese2016-01-14-20/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds runtime detection of the Marvell UART boot-mode (xmodem protocol). If this boot-mode is detected, SPL will return to the BootROM to continue the UART booting. With this patch its now possible, to generate a U-Boot image that can be booted either from the strapped boot-device (e.g. SPI NOR, MMC, etc) or via the xmodem protocol from the UART. In the UART case, the kwboot tool will dynamically insert the UART boot-device type into the image. And also patch the load address in the header, so that the mkimage header will be skipped (as its not expected by the Marvell BootROM). This simplifies the development for Armada XP / 38x based boards. As no special images need to be generated by selecting the MVEBU_BOOTROM_UARTBOOT Kconfig option. Since the Kconfig option MVEBU_BOOTROM_UARTBOOT is not needed any more, its now completely removed.
