[edk2-devel] [PATCH edk2-platforms 2/2] Platform/StMmRpmb: Switch to MbedTls for crypto

["Ard Biesheuvel via groups.io" <ardb+git=google.com@groups.io>]

From: Ard Biesheuvel <ardb@kernel.org>

MbedTls is much smaller than OpenSSL, and does not require a softfloat
library on 32-bit ARM. So use that instead.

Note that we still need to resolve OpensslLib, given that MbedTlsLib has
a dependency on it (but only for SM3 digital signatures, which are not
used here)
