[PATCH v2 10/11] fpga: Add flag to indicate bitstream needs decompression Alan Tull <atull@kernel.org> - 2017-06-14 17:40 +0200

| Subject | [PATCH v2 10/11] fpga: Add flag to indicate bitstream needs decompression |
| Message-ID | <tSiyK-6WY-13@gated-at.bofh.it> |
From: Anatolij Gustschin <agust@denx.de>
Add a flag that is passed to the write_init() callback, indicating
that the bitstream is compressed.
The low-level driver will deal with the flag, or return an error,
if compressed bitstreams are not supported.
