Subject: TPM: increase default TPM buffer
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=7f366784f5c2b8fc0658b5b374f4c63ee42c789f;p=linux-edison.git

TPM: increase default TPM buffer

The TPM Working Group requested this communication buffer increase given that a
particular TPM vendor can support a TPM_SHA1Start command input bigger than the
current size.
