| * | x86: qemu: add fw_cfg supportMiao Yan2016-01-134-1/+380
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QEMU fw_cfg interface allows the guest to retrieve various data information from QEMU. For example, APCI/SMBios tables, number of online cpus, kernel data and command line, etc. This patch adds support for QEMU fw_cfg interface.

However, AArch64 uses a different startup file, and the same change was not made to it. This leaves gd uninitialized on AArch64, which typically leads to hangs or crashes. This change fixes that.

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>

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.

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.

To get even better performance (bootup time), lets enable the L2 cache in U-Boot. This code was taken from the Linux kernel. A performance gain was measured on the DB-MV784MP-GP board by testing with tftpboot and sata commands. This patch also cleans up the L2 cache related code. And makes sure that the L2 cache is only disabled once. Please note that A38x still runs with L2 cache disabled. And needs to be enabled for this SoC in a separate patch if needed or desired.

As all MVEBU boards using this driver are converted with this patch, the non-driver-model code can be removed completely. 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. When this is done, the E1000 driver can be enabled again.

Currently only serial is supported. Other drivers will follow. This patch also adds the necessary config values for the DEBUG UART to the MVEBU defconfig files. This came in handy while implementing this DM support. Additionally, the mvebu specific SPL linker script is removed and this common one is used instead: arch/arm/cpu/u-boot-spl.lds This common linker script already handles all special cases. No need to reinvent the wheel for MVEBU here.

Because SPL_DM requires malloc(), enable CONFIG_SPL_SYS_MALLOC_SIMPLE for LPC32xx boards. The change adds about 5KB to the resulting SPL image (for devkit3250 board SPL image is increased from 10672 to 15608 bytes).

Due to specific of DM NS16550 device description UART clock can not be got in runtime and by default it is set to 13MHz, if board PERIPH_CLK is different, this should be specified in board configuration file. For SPL builds HSUARTs are disabled and non-DM NS16550 driver is compiled, if needed. The change also updates default configs of devkit3250 and work_92105 boards to reflect updates in platform files.

Therefore arch_setup_gd(), which is supposed to set r9, may actually have no effect, causing U-Boot to use a bad address to access GD. Fix this by never calling arch_setup_gd() for ARM, and instead setting r9 in arch/arm/lib/crt0.S, to the value returned by board_init_f_alloc_reserve().
