2016-01-14arm: mvebu: Make local structs static constStefan Roese
As these structs are local only and const, declare them accordingly. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr> Cc: Dirk Eibach <dirk.eibach@gdsys.cc> Cc: Phil Sutter <phil@nwl.cc> Cc: Kevin Smith <kevin.smith@elecsyscorp.com>

2016-01-14arm: mvebu: Move SoC selection (A38X vs AXP) into KconfigStefan Roese
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. And CONFIG_DDR3 is removed, as its not referenced anywhere. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>

2016-01-14arm: mvebu: Don't include "netdev.h" in cpu.cStefan Roese
This is not needed any more since the switch to DM / DTS network initialization on MVEBU. Lets remove it, as it otherwise leads to compilation warning when CONFIG_NET is not enabled. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
2016-01-14arm: mvebu: Add support for MV78260Stefan Roese

2016-01-14arm: mvebu: Don't disable cache at startup on Armada XP at allStefan Roese
This patch leaces the cache configuration untouched for the AXP in the setup done by the BootROM. Resulting in the cache still being enabled at the startup of U-Boot. This leads to a slightly faster boot to the U-Boot prompt (or Linux of course). Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
2016-01-14arm: mvebu: Don't call arch_cpu_init() from SPL at allStefan Roese
This patch removes the call to arch_cpu_init() in the SPL U-Boot version. As SPL does not need all the configuration done in this function. And also does not need the reconfiguration of the internal register address to 0xf1000000. This will be done by the main U-Boot later on. This also fixes a problem with the timer not beeing initialized on AXP, as needed for the mdelay in the setup_usb_phys(). This will now only be called once in main U-Boot.

2016-01-14arm: mvebu: Add v7_outer_cache_disable function for AXP & A38xStefan Roese
Add functionality to correctly disable the L2 cache on the Armada XP and 38x platforms. Without this, booting into Linux on ClearFog (A38x) results in a hangup without any output on the serial console at all. Even with earlyprintk enabled.

2016-01-14arm: mvebu: Enable L2 cache on Armada XPStefan Roese
Until now, the L2 cache was never enabled again in U-Boot. 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.

2016-01-14arm: mvebu: Add SolidRun ClearFog Armada 38x initial supportStefan Roese
This patch adds basic support for the SolidRun ClearFog Armada 38x based board to mainline U-Boot. Supported interfaces / devices are: - DDR3 - UART - MMC - Ethernet port 0 (connected to dedicated PHY) - I2C The included DT source was taken from Russell King's ftp server: http://www.home.arm.linux.org.uk/~rmk/clearfog/ With only minor modifications, like the addition of some aliases and the "u-boot,dm-pre-reloc" property.

2016-01-14net: mvneta: Convert to driver modelStefan Roese
Update this driver to support driver model. 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.

2016-01-14arm: mvebu: Add SPI driver model supportStefan Roese
This patch enables the DM support for the SPI driver and the SPI NOR flash chips. Some MVEBU boards boot from SPI NOR, so adding the aliases and enabling CONFIG_DM_SEQ_ALIAS is needed here.

2016-01-14arm: mvebu: Add DM and OF_CONTROL support to SPLStefan Roese
This patch adds full DM support to the SPL on MVEBU. 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.

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.

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.

2015-10-01arm: mvebu: Fix internal register config on A38xStefan Roese
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.

This patch enables the USB EHCI support for the Marvell Armada XP (AXP) SoCs. In compatism to the Armada 38x (A38x), the AXP needs to configure the USB PLL and the USB PHY's specifically in U-Boot. The A38x has done this already in the bin_hdr (SPL U-Boot). Without this, accessing the controller registers in U-Boot or Linux will hang the CPU. Additionally, the AXP uses a different USB EHCI base address. This patch also takes care of this by runtime SoC detection in the Marvell EHCI driver.

Only with disabled MMU its possible to switch the base register address on Armada 38x. Without this the SDRAM located at >= 0x4000.0000 is also not accessible, as its still locked to cache. So to fully release / unlock this area from cache, we need to first flush all caches, then disable the MMU and disable the L2 cache. On Armada XP this does not seem to be needed.
