[U-Boot][PATCH v5 0/5] Improve fpga cmd usage information

[Ibai Erkiaga]

  Current usage information is not read friendly specially when all the
  options are selected. This series fix some of the issues in the info,
  aligment and overlapping issues, excess of verbosity on the loads...

  Additionally Xilinx exclusive command dependencies are included to
  remove text stating Xilinx Only

  The output looks like this now:

  fpga - loadable FPGA image support

  Usage:
  fpga info   [dev]                  List known device information
  fpga dump   <dev> <address> <size> Load device to memory buffer
  fpga load   <dev> <address> <size> Load device from memory buffer
  fpga loadb  <dev> <address> <size> Load device from bitstream buffer
  fpga loadp  <dev> <address> <size> Load device from memory buffer
              with partial bitstream
  fpga loadbp <dev> <address> <size> Load device from bitstream buffer
               with partial bitstream
  fpga loadfs <dev> <address> <size> <blocksize> <interface> [<dev[:part]>] <filename>
              Load device from filesystem (FAT by default)
  fpga loadmk <dev> <address>        Load device generated with mkimage
              NOTE: loadmk operating on FIT must include subimage unit
              name in the form of addr:<subimg_uname>
  fpga loads  <dev> <address> <size> <authflag> <encflag> [Userkey address]
              Load device from memory buffer with secure bistream
              (authenticated/encrypted/both)
              -authflag: 0 for OCM, 1 for DDR, 2 for no authentication
              (specifies where to perform authentication)
              -encflag: 0 for device key, 1 for user key, 2 for no encryption
              -Userkey address: address where user key is stored
              NOTE: secure bitstream has to be created using Xilinx bootgen tool

Changes in v5:
- Reorder KConfig to ensure commands are listed in the same order as the
code.
- Clarify the bitstream file type for load/loadb/loadp/loadbp commands

Changes in v4:
- Split 4th patch into two, one for existing symbol dependencies and one
for the new symbol

Changes in v3:
- Split 3rd patch into two, resorting commands and Kconfig changes

Changes in v2:
- Tabs replaced by spaces
- fpga command added on each option similar to other commands like sf
- Dependencies to Xilinx only commands added in Kconfig

Ibai Erkiaga (5):
  fpga: fix alignment on fpga cmd usage info
  fpga: improve loads usage information
  fpga: resort fpga commands
  fpga: xilinx exclusive commands
  fpga: add new symbol for fpga_loadb
