| * | armv8: semihosting: add a command to load semihosted images | Linus Walleij | 2015-03-28 | 1 | -20/+5 |
| | | | | | | | | | | | | | | | Instead of sprinkling custom code and calls over the Vexpress64 boardfile, create a command that loads images using semihosting just like we would load from flash memory of over the network, using a special command: smhload <image> <address> This will make it possible to remove some custom calls and code and make the boot easier.

| * | arm: Add support for semihosting for armv8 fastmodel targets. | Darwin Rambo | 2014-07-03 | 1 | -0/+54 |
| 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.
