commit f592cc5794747b81e53b53dd6e80219ee25f0611 upstream.
Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned
addresses associated with it. These control voltage, enable state, mode,
and in legacy targets, voltage headroom. The current in-flight request
checking logic looks for exact address matches. Requests for different
addresses of the same RPMh resource as thus not detected as in-flight.
Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight
request check for VRM requests by ignoring the address offset.
This ensures that only one request is allowed to be in-flight for a given
VRM resource. This is needed to avoid scenarios where request commands are
carried out by RPMh hardware out-of-order leading to LDO regulator
over-current protection triggering.

[ Upstream commit 914f8b228ede709274b8c80514b352248ec9da00 ]
This adds a function to update a CGR with new parameters. qman_create_cgr
can almost be used for this (with flags=0), but it's not suitable because
it also registers the callback function. The _safe variant was modeled off
of qman_cgr_delete_safe. However, we handle multiple arguments and a return
value.

Current DCP driver implementation doesn't support AES OTP CRYPTO_KEY. otp_unique_key & otp_crypto_key handles are generated by U-boot RNG driver and on each reboot cycle, device tree fix-up is done using RNG. OpenSSL application can input device tree fixed up 16 byte number for crypto operations. Tested on i.MX6ULL EVK with commands below. - Encrypt using UNIQUE_KEY: $ openssl aes-128-ecb -p -nosalt -nopad -K "$(hexdump -v -e '"" 1/1 "%02X"'\ /proc/device-tree/soc/bus@2200000/crypto@2280000/otp_unique_key)" -in \ openssl_test.txt -out my_encrypted_secret.bin - Decrypt using UNIQUE_KEY: $ openssl aes-128-ecb -d -p -nosalt -nopad -K "$(hexdump -v -e '"" 1/1 "%02X"'\ /proc/device-tree/soc/bus@2200000/crypto@2280000/otp_unique_key)" -in \ my_encrypted_secret.bin -out openssl_decrypt_test.txt - Encrypt using CRYPTO_KEY: $ openssl aes-128-ecb -p -nosalt -nopad -K "$(hexdump -v -e '"" 1/1 "%02X"'\ /proc/device-tree/soc/bus@2200000/crypto@2280000/otp_crypto_key)" -in \ openssl_test.txt -out my_encrypted_secret.bin - Decrypt using CRYPTO_KEY: $ openssl aes-128-ecb -d -p -nosalt -nopad -K "$(hexdump -v -e '"" 1/1 "%02X"'\ /proc/device-tree/soc/bus@2200000/crypto@2280000/otp_crypto_key)" -in \ my_encrypted_secret.bin -out openssl_decrypt_test.txt Signed-off-by: Kshitiz Varshney <kshitiz.varshney@nxp.com> Reviewed by: Gaurav Jain <gaurav.jain@nxp.com>
