Enable support for DFU over USB. This requires to enable USB gadget, DWC2 UDC OTG driver and DFU command. DFU entities are defined for the following firmware objects: u-boot.bin, uboot.env, config.txt, and zImage/Image.

/*
|
|
* Memory layout for where various images get loaded by boot scripts:
|
|
*
|
|
* I suspect address 0 is used as the SMP pen on the RPi2, so avoid this.
|
|
*
|
|
* Older versions of the boot firmware place the firmware-loaded DTB at 0x100,
|
|
* newer versions place it in high memory. So prevent U-Boot from doing its own
|
|
* DTB + initrd relocation so that we won't accidentally relocate the initrd
|
|
* over the firmware-loaded DTB and generally try to lay out things starting
|
|
* from the bottom of RAM.
|
|
*
|
|
* kernel_addr_r has different constraints on ARM and Aarch64. For 32-bit ARM,
|
|
* it must be within the first 128M of RAM in order for the kernel's
|
|
* CONFIG_AUTO_ZRELADDR option to work. The kernel itself will be decompressed
|
|
* to 0x8000 but the decompressor clobbers 0x4000-0x8000 as well. The
|
|
* decompressor also likes to relocate itself to right past the end of the
|
|
* decompressed kernel, so in total the sum of the compressed and and
|
|
* decompressed kernel needs to be reserved.
|
|
*
|
|
* For Aarch64, the kernel image is uncompressed and must be loaded at
|
|
* text_offset bytes (specified in the header of the Image) into a 2MB
|
|
* boundary. The 'booti' command relocates the image if necessary. Linux uses
|
|
* a default text_offset of 0x80000. In summary, loading at 0x80000
|
|
* satisfies all these constraints and reserving memory up to 0x02400000
|
|
* permits fairly large (roughly 36M) kernels.
|
|
*
|
|
* scriptaddr and pxefile_addr_r can be pretty much anywhere that doesn't
|
|
* conflict with something else. Reserving 1M for each of them at
|
|
* 0x02400000-0x02500000 and 0x02500000-0x02600000 should be plenty.
|
|
*
|
|
* On ARM, both the DTB and any possible initrd must be loaded such that they
|
|
* fit inside the lowmem mapping in Linux. In practice, this usually means not
|
|
* more than ~700M away from the start of the kernel image but this number can
|
|
* be larger OR smaller depending on e.g. the 'vmalloc=xxxM' command line
|
|
* parameter given to the kernel. So reserving memory from low to high
|
|
* satisfies this constraint again. Reserving 1M at 0x02600000-0x02700000 for
|
|
* the DTB leaves rest of the free RAM to the initrd starting at 0x02700000.
|
|
* Even with the smallest possible CPU-GPU memory split of the CPU getting
|
|
* only 64M, the remaining 25M starting at 0x02700000 should allow quite
|
|
* large initrds before they start colliding with U-Boot.
