From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Sat, 6 Feb 2021 14:23:34 -0700 Subject: [PATCH v4 03/11] tpm: Add debugging of request in tpm_sendrecv_command() In-Reply-To: <20210206212343.3567308-1-sjg@chromium.org> References: <20210206212343.3567308-1-sjg@chromium.org> Message-ID: <20210206212343.3567308-4-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The response is shown but not the request. Update the code to show both if debugging is enabled. Use a 'uint' type for size so it matches the register-word size on both 32- and 64-bit machines.
