Subject: [PATCH v1 4/6] bus: mhi: core: Use common name for BHI firmware load function
Date: Tue, 19 May 2020 17:30:29 -0700	[thread overview]
Message-ID: <1589934631-22752-5-git-send-email-bbhatt@codeaurora.org> (raw)
In-Reply-To: <1589934631-22752-1-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). Moreover, its contents do not
indicate anything regarding support for a specific set of images. Since
it can be used for any image download over BHI, it can be appropriately
renamed mhi_fw_load_bhi() instead.
