* env_fat: use get_device_and_partition() during env save and loadWu, Josh2014-07-07-60/+34
| | | | | | | | | | | | | | | | | | | | | | Use get_device_and_partition() is better since: 1. It will call the device initialize function internally. So we can remove the mmc intialization code to save many lines. 2. It is used by fatls/fatload/fatwrite. So saveenv & load env should use it too. 3. It can parse the "D:P", "D", "D:", "D:auto" string to get correct device and partition information by run-time. Also we remove the FAT_ENV_DEVICE and FAT_ENV_PART. We use a string: FAT_ENV_DEVICE_AND_PART. For at91sam9m10g45ek, it is "0". That means use device 0 and if: a)device 0 has no partition table, use the whole device as a FAT file system. b)device 0 has partittion table, use the partition #1. Refer to the commit: 10a37fd7a4 for details of device & partition string. Signed-off-by: Josh Wu <josh.wu@atmel.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>

| | | | | | | | | | | | | J6 EVM can be built with UART3 as console, but currently there's nothing muxing UART3 correctly. Likely this only works because, based on commit log, author was only testing with UART3 boot and - I assume - ROM code leave UART3 correctly muxed in that case. If we want to boot from MMC and still use UART3 as console, then we need to mux those signals correctly. Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra I2C controller's TX FIFO contains 32-bit words. If the final FIFO entry of a transaction contains fewer than 4 bytes, the driver currently fills the unused FIFO bytes with uninitialized data. This can be confusing when reading back the FIFO content for debugging purposes. Solve this by explicitly initializing the variable containing FIFO data before filling it (partially) with data. With this change, send_recv_packets()'s loop's if (is_write) code mirrors the else (i.e. read) branch. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Yen Lin <yelin@nvidia.com>

* | 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.
