* sunxi: use random parts of SID to set ethaddrJonathan Liu2014-07-18-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | Similar to the USB NIC found on OMAP5uEVM, PandaBoard and BeagleBoard-XM boards, the sunxi SoCs have a NIC onboard without an embedded MAC address. Just like the omap used on these boards, the sunxi SoCs do have a unique chip id, in the form of the 128 bit SID register: http://linux-sunxi.org/SID_Register_Guide So mimick the BeagleBoard-XM board code (commit 548a64d8) and use the chip id to generate a unique fixed MAC address. We check for the SID not being all 0, since some early A20 batches shipped without having there SID programmed. Note we use specific parts of the 128 bits, since some parts indicate the SoC family / revision, and thus are fixed. The algorithm for this was taken from the linux-sunxi.org kernels.

* sunxi: Remove mmc DMA supportHans de Goede2014-07-06-135/+7
| | | | | | | | | | | | | | | | The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the dma descriptors on the stack, and then exits while the dma transfer is in progress, so the dma engine is reading stack memory which at that point may be re-used. So far we've gotten away with this by luck, but recent u-boot changes have shifted the stack start address by 16 bytes, which combined with dma alignment now exposes this problem. Since we end up just busy waiting for the dma engine anyway, this commit fixes things by simply removing the dma code, resulting in smaller bug-free code.

This patch fixes this bug.

* arm: Add support for semihosting for armv8 fastmodel targets.Darwin Rambo2014-07-03-12/+462
| | | | | | | | | | | | | | | | | | | | | | The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generic board support is now enabled for Exynos 4, and if any init function returns an error then the init process is stopped. This makes a boot issue on the Trats and Trats2 devices. If the device is supplied by USB cable or an external power supply then it can't boot because function exynos_power_init returns an error. Now this function returns 0 if battery is not connected.
