Subject: [PATCH v5 24/29] image: Split up boot_get_ramdisk()
Date: Sat, 25 Sep 2021 19:43:37 -0600 [thread overview]
Message-ID: <20210926014342.127913-18-sjg@chromium.org> (raw)
In-Reply-To: <20210926014342.127913-1-sjg@chromium.org>
This function is far too long. Before trying to remove #ifdefs, split out
the code that deals with selecting the ramdisk into a separate function.
Leave the code indented as it was for easier review. The next patch cleans
this up along with checkpatch violations.
Signed-off-by: Simon Glass <sjg@chromium.org>

Changes in v5:
- Drop rd_load since it is not used
Changes in v2:
- Drop unnecessary setting of rd_len, etc.
