Channagoud kadabi 38a5ecb756 fix(ufs): fix cache maintenance issues
Fix software cache maintenance issues that can happen when
cpu prefetches data before DMA operations are complete.
This change fixes two cases one for ufs_read_blocks and
other for ufs_check_resp, in both cases invalidation of
buffer was done before the DMA operation completed.
This caused cpu prefetcher to bring data into cache
before DMA completed and caused UFS read failures.
The changes also removes unwanted cache operations to
local variable utrd which is not consumed by UFS host
controller and zeroing out buffer in ufs_read_capacity.

Trusted Firmware-A

Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.

TF-A implements Arm interface standards, including:

The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.

In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.

Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
