* common: Pass the boot device into spl_boot_mode()Marek Vasut2016-06-26-1/+1
| | | | | | | | | | | | | | | | | | The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

* mvebu: Support Synology DS414Phil Sutter2016-01-14-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the MV78230 based DS414 NAS by Synology. 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>

* drivers/pci/pci_mvebu: Fix for boards with X4 lanesPhil Sutter2016-01-14-0/+2
| | | | | | | | | | | | | | | | | 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.

* arm: mvebu: Move SoC selection (A38X vs AXP) into KconfigStefan Roese2016-01-14-14/+25
| | | | | | | | | | | | | | | | | | Until now, the SoC selection for the ARCH_MVEBU platforms has been done in the config header. Using CONFIG_ARMADA_XP in a non-clear way. As it needed to get selected for AXP and A38x based boards. This patch now changes this to move the SoC selection to Kconfig. And also uses CONFIG_ARCH_MVEBU as a common define for both AXP and A38x. This makes things a bit clearer - especially for new board additions. Additionally the defines CONFIG_SYS_MVEBU_DDR_AXP and CONFIG_SYS_MVEBU_DDR_A38X are replaced with the already available CONFIG_ARMADA_38X and CONFIG_ARMADA_XP.

This is also the reason why this patch is quite big and includes a) the driver change and b) the platform change. As its not git-bisect save otherwise. With this conversion, some parameters are now extracted from the DT instread of using the config header defines. The supported properties right now are: PHY-mode ("phy-mode") and PHY-address ("reg"). The base addresses for the ethernet controllers can be removed from the header files as well. Please note that this patch also removes the E1000 network driver from some MVEBU config headers. This is necessary, as with DM_ETH configured and the e1000 driver enabled, the PCI driver also needs to support DM. But the MVEBU PCI(e) driver still needs to get ported to DM.

* arm: mvebu: Add DM (driver model) supportStefan Roese2015-10-21-3/+0
| | | | | | | | | | | | | | | | This patch adds driver model support for some Marvell MVEBU SoC's. Including Armada XP and 38x. All 3 currently mainlined boards are converted. DM is now selected automatically for MVEBU platforms. With this DM support now available for MVEBU, hardcoding the base addresses and other information is not necessary any more. Probing should be done by using the values provided via the device tree now instead. For this the driver also need to be converted to DM. Patches for some of the drivers will follow.

* arm: mvebu: Do not call board_init_r() from board_init_f()Stefan Roese2015-10-21-2/+0
| | | | | | | | | | | | | Instead of calling board_init_r() directly from board_init_f(), just return from board_init_f(). This will make the code continue executing in crt0.S _main(), from which the board_init_r() is called. This patch aligns the MVEBU SPL with the correct SPL design as well as reduces the stack utilisation slightly.

* arm: mvebu: Only set CONFIG_SKIP_LOWLEVEL_INIT for SPLStefan Roese2015-10-21-12/+19
| | | | | | | | | When running on the AXP I sometimes noticed a strange behavior. As some characters are not echoed on the U-Boot prompt. Not disabling the lowlevel_init code, especially calling cpu_init_cp15() in the main U-Boot seems to solve this issue. Signed-off-by: Stefan Roese <sr@denx.de>
* arm: mvebu: Add option to use UART xmodem protocol via kwbootStefan Roese2015-10-21-1/+54
| | | | | | | | | | | | | | | | | | | | | | This patch enables the use of the kwboot tool, to boot mainline U-Boot on the Marvell Armada XP/38x SoC's. This is done by returning to the SoC's BootROM after SPL has initialized the SDRAM. We need to make sure to not reconfigure the internal register space and MBARs. Otherwise the BootROM will not be able to continue after SPL jumps back to it. To use this feature, please don't forget to change the BOOT_FROM line in your board specfic kwbimage.cfg file this way: BOOT_FROM uart Tested on these Marvell eval boards: DB-MV784MP-GP - Armada XP DB-88F6820-GP - Armada 38x Signed-off-by: Stefan Roese <sr@denx.de> Cc: Dirk Eibach <eibach@gdsys.de> Cc: Kevin Smith <kevin.smith@elecsyscorp.com> Cc: Luka Perkov <luka.perkov@sartura.hr>

| | | | | | | | | | | | | As reported by Simon Guinot, commit ade741b3 "arm: mvebu: Call timer_init early before PHY and DDR init" breaks Kirkwood platforms. As the static variable "init_done" is not available at that early boot time. This patch moves it to explicitly to the data section, making it available at that time.

* arm: mvebu: Fix internal register config on A38xStefan Roese2015-10-01-14/+22
| | | | | | | | | | | | | | | | | Currently booting on A38x is broken. As the current code tries to detect the SoC family to disable the MMU for the A38x at runtime. But before the internal registers are switched to the new location (0xf100.0000), this runtime detection does not work. As all macros / defines are already assigned to the new location at 0xf100.0000. But the registers are sill mapped to the default location at 0xd000.0000. This patch now makes sure, no such runtime detection is used before the internal registers are configured to the new location. After this, the remaining cache cleanup is executed.

* pci: mvebu: Add PCIe driverAnton Schubert2015-08-17-8/+0
| | | | | | | | | | | | | | | | | | | This adds a PCI driver for the controllers found on Marvell MVEBU SoCs. Besides the driver, this patch also removes the statically defined PCI MBUS windows. As they are not needed anymore, since this PCIe driver now creates the windows dynamically. Tested on Armada XP db-mv784mp-gp eval board using an Intel E1000 PCIe card in all 3 PCIe slots. And on the Armada 38x db-88f6820-gp eval board using this Intel E1000 PCIe card in the PCIe 0 slot. This port was done in cooperation with Anton Schubert.
