Subject: [PATCH v3 01/12] bus: mhi: core: Use appropriate names for firmware load functions
Date: Thu, 29 Oct 2020 21:10:46 -0700	[thread overview]
Message-ID: <1604031057-32820-2-git-send-email-bbhatt@codeaurora.org> (raw)
In-Reply-To: <1604031057-32820-1-git-send-email-bbhatt@codeaurora.org>

mhi_fw_load_sbl() function is currently used to transfer SBL or EDL
images over BHI (Boot Host Interface). Same goes with mhi_fw_load_amss()
which uses BHIe. However, the contents of these functions do not
indicate support for a specific set of images. Since these can be used
for any image download over BHI or BHIe, rename them based on the
protocol used.
