Subject: [PATCH] powerpc/xmon: Enable breakpoints on 8xx
Date: Wed, 23 Dec 2020 09:38:48 +0000 (UTC)	[thread overview]
Message-ID: <b0607f1113d1558e73476bb06db0ee16d31a6e5b.1608716197.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <e4471bf81089252470efb3eed735d71a5b32adbd.1608716197.git.christophe.leroy@csgroup.eu>

Since commit 4ad8622dc548 ("powerpc/8xx: Implement hw_breakpoint"),
8xx has breakpoints so there is no reason to opt breakpoint logic
out of xmon for the 8xx.
