Subject: [PATCH 03/11] board: freescale: p1_p2_rdb_pc: Fix parsing negated upper 4 bits from boot input data
Date: Thu, 7 Apr 2022 12:16:16 +0200 [thread overview]
Message-ID: <20220407101624.15850-4-pali@kernel.org> (raw)
In-Reply-To: <20220407101624.15850-1-pali@kernel.org>
On some boards upper 4 bits of i2c boot input data (register 0) are
negated. So negate read input data back prior processing them.
Fixes printing correct rom_loc: value.
