Subject: [PATCH v2 1/3] MIPS: head.S: Always jump to kernel_entry at head of text
Date: Wed, 27 May 2020 14:34:32 +0800	[thread overview]
Message-ID: <20200527063438.391949-2-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20200527063438.391949-1-jiaxun.yang@flygoat.com>

Buggy loaders like early version of PMON2000 sometimes ignore
elf_entry and goto start of text directly.

That would help with dealing with these loaders.
