[PATCH v1 0/5] xen/arm: Add support for S32CC platforms and LINFlexD UART

["Andrei Cherechesu (OSS)" <andrei.cherechesu@xxxxxxxxxxx>]

From: Andrei Cherechesu <andrei.cherechesu@xxxxxxx>

This patch series adds support for NXP Automotive S32CC platform
family, which includes S32G [0] and S32R [1].

First patch adds the driver for the NXP LINFlexD UART, available
on S32V, S32G and S32R automotive processors. The compatibles in
the driver match the ones in upstream Linux [2]. The second patch
adds early printk support via LINFlexD UART.

The third patch introduces the S32CC platforms and adds the
platform-specific code, which enables forwarding SCMI over SMC
calls to software running at EL3. The fourth patch adds support
for an early printk menuconfig option for S32CC platforms using
the LINFlexD UART.

The fifth patch enables the workaround for ARM Cortex-A53 erratum
1530924, already implemented in Xen for other cores via
ARM64_WORKAROUND_AT_SPECULATE.
