That's plenty: existing machines will only ever set this value to EXYNOS4210_NCPUS (2). But the compiler can't always figure that out, so some[*] gcc9 versions emit -Wformat-truncation warnings. We can fix that by hinting the constraint to the compiler with a suitably placed assert(). [*] The bizarre thing here, is that I've long gotten these warnings compiling in a 32-bit x86 container as host - Fedora 30 with gcc-9.2.1-1.fc30.i686 - but it compiles just fine on my normal x86_64 host - Fedora 30 with and gcc-9.2.1-1.fc30.x86_64.

This is what the model supports today. - Pool Buffer mode, using an internal SRAM to transfer multiple bytes in the same command sequence. Each SoC has different SRAM characteristics. On the AST2400, 2048 bytes of SRAM are available at offset 0x800 of the controller AHB window. The pool buffer can be configured from 1 to 256 bytes per bus. On the AST2500, the SRAM is at offset 0x200 and the pool buffer is of 16 bytes per bus. On the AST2600, the SRAM is at offset 0xC00 and the pool buffer is of 32 bytes per bus. It can be splitted in two for TX and RX but the current model does not add support for it as it it unused by known drivers.

The NSACR.{CP11,CP10} bits define the exception level required to access the FPU in Non-Secure mode. Without these bits set, the CPU will give an undefined exception trap on the first FPU access for the secondary cores under Linux. This is necessary because in this power-control codepath QEMU is effectively emulating a bit of EL3 firmware, and has to set the CPU up as the EL3 firmware would.

Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.
