Subject: [PATCH 2/3] powerpc: mpc85xx: Rename _start_e500 symbol to _start
Date: Sun, 3 Apr 2022 00:05:09 +0200 [thread overview]
Message-ID: <20220402220510.17879-3-pali@kernel.org> (raw)
In-Reply-To: <20220402220510.17879-1-pali@kernel.org>
The real entry point is _start_e500. There is no _start symbol at all. So
rename _start_e500 to _start for convension that _start symbol is used as
entry point.
