Hi Heinrich
[...]
Why are we using COMMAND_BUFFER_SIZE throughout the TPM code if the required buffer size for commands and responses can be read from the TPM device?
I think the logic is that 256b is enough for the basic commands we needed. I can change that here. Get the TPM response during efi_tcg2_register() and use that for the rest of the code?
A clarification is needed here, which I forgot on my initial response. The tpm library in U-boot is using the same buffer and length. That's the reason I used the same response buffer size. The reply is copied from the internal buffer defined in tpm2_get_capability() to our response buffer. So unless we change the TPM internals changing the EFI part will make no difference. That being said I don't mind changing the EFI code since it will be future-proof, against the tpm code changes. Thoughts?
