This patch adds the logic to properly handle doorbells that come in when interrupts have been soft disabled and to replay them when interrupts are re-enabled: - masked_##_H##interrupt is modified to leave interrupts enabled when a doorbell has come in since doorbells are edge sensitive and as such won't be automatically re-raised. - __check_irq_replay now tests if a doorbell happened on book3s, and returns either 0xe80 or 0xa00 depending on whether we are the hypervisor or not. - restore_check_irq_replay now tests for the two possible server doorbell vector numbers to replay. - __replay_interrupt also adds tests for the two server doorbell vector numbers, and is modified to use a compare instruction rather than an andi. on the single bit difference between 0x500 and 0x900. The last two use a CPU feature section to avoid needlessly testing against the hypervisor vector if it is not the hypervisor, and vice versa.

There are a few key differences between doorbells on server compared with embedded that we care about on Linux, namely: - We have a new msgsndp instruction for directed privileged doorbells. msgsnd is used for directed hypervisor doorbells. - The tag we use in the instruction is the Thread Identification Register of the recipient thread (since server doorbells can only occur between threads within a single core), and is only 7 bits wide. - A new message type is introduced for server doorbells (none of the existing book3e message types are currently supported on book3s).

With commit 384a2902 (ARM: gic: use a private mapping for CPU target interfaces), wake-up IPIs now go to all cores as the gic cpu interface numbering may not follow core numbering. This broke secondary boot on highbank since the boot address was already set for all secondary cores, this caused all cores to boot before the kernel was ready. Fix this by moving the setting of the jump address to highbank_boot_secondary instead of highbank_smp_prepare_cpus and highbank_cpu_die. Also, clear the address when we boot. This prevents cores from booting before they are actually triggered and is also necessary to get suspend/resume to work.

We originally thought that the MV78230 variant of the Armada XP had four Ethernet interfaces, like the other variants MV78260 and MV78460. In fact, this is not true, and the MV78230 has only three Ethernet interfaces. So, the definitions of the Ethernet interfaces is now done as follows: * armada-370-xp.dtsi: definitions of the first two interfaces, that are common to Armada 370 and Armada XP * armada-xp.dtsi: definition of the third interface, common to all Armada XP variants. * armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of the fourth interface.

The UART controller used in the Armada 370 and Armada XP SoCs is the Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The improper use of the ns16550 can lead to a kernel oops during boot if a character is sent to the UART before the initialization of the driver. The DW APB has an extra interrupt that gets raised when writing to the LCR when busy. This explains why we need to use dw-apb-uart driver to handle this.
