From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Thu, 4 Mar 2021 06:51:14 -0700 Subject: [PATCH v4 38/42] spl: Convert spl_fit to work with sandbox In-Reply-To: <20210304135118.643277-1-sjg@chromium.org> References: <20210304135118.643277-1-sjg@chromium.org> Message-ID: <20210304135118.643277-37-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de At present this casts addresses to pointers so cannot work with sandbox. Update the code to use map_sysmem() instead. As part of this change, the existing load_ptr is renamed to src_ptr since it is not a pointer to load_addr. It is confusing to use a similar name for something that is not actually related. For the alignment code, ALIGN() is used instead of open-coded alignment. Add a comment to the line that casts away a const. Use a (new) load_ptr variable to access memory at address load_addr.
