Having DEBUG_CONSOLE enabled without enabling DEBUG_CONSOLE_A53 doesn't make sense (since UART pinmux/clock configuration is applied for UART only when DEBUG_CONSOLE_A53 is enabled). Enable DEBUG_CONSOLE_A53 if DEBUG_CONSOLE is enabled. Signed-off-by: Igor Opaniuk <igor.opaniuk@gmail.com> Change-Id: I8ca411d5544658b9bcc39e5340ec042c51088b96

This removes hardcoded iomux/clk/addr configuration for debug uart, provides possibility (as a workaround, till that information isn't provided via DT) to set this configuration during compile time via IMX_DEBUG_UART build flag. Usage: $ make PLAT=imx8qm IMX_DEBUG_UART=1 bl31 Signed-off-by: Igor Opaniuk <igor.opaniuk@gmail.com> Change-Id: Ib5f5dd81ba0c8ad2b2dc5647ec75629072f511c5

Platform defines are already provided by the build system so let's not duplicate them. Change-Id: Icf1ea76c3c3213e27b447c95e2b22b961fa7693e Signed-off-by: Leonard Crestez <leonard.crestez@nxp.com>

Current implementation of i.MX8QM power management related features does NOT optimize power number, all system resources like CCI, DDR, and A cluster etc. are kept in STBY mode (powered ON) when system suspend or CPU hotplug. To lower the power number, OFF mode should be adopted for those system resources whenever they can be OFF, A cluster will be OFF if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF if system suspend, IRQ steer can be OFF if the wakeup source is belonged to system controller partition, so wakeup source runtime check is used to determine if IRQ steer can be OFF before system suspend. If resources are powered off for suspend, they should be restored properly after system resume. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca339 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.
