I think a better reference is https://github.com/hno/Allwinner-Info/blob/master/FEL-usb/USB-protocol.txt
Yes, very likely. Except that I'm a little bit concerned about the long term availability of this link (which is a personal repository on github).
I have quoted the relevant parts of the memory map information in the commit message. But now I wonder if we should replicate the Allwinner FEL mode memory map information somewhere in the u-boot documentation?
Or move it to the sunxi wiki?
[...]
- /* Pass control to the 's_init()' function */
- b s_init
Since this code is in arm mode and s_init will, I think, be in Thumb mode after this patch shouldn't this be a bx?
Since this branch instruction refers to an external symbol, the linker has all the necessary information and takes care of handling Thumb interworking whenever it is necessary.
OK.
