This is what we want to be doing for host-OS-feature-checks anyway, but it also fixes a problem with building for macOS with the most recent XCode SDK on a Catalina host. On that configuration, 'preadv()' is provided as a weak symbol, so that programs can be built with optional support for it and make a runtime availability check to see whether the preadv() they have is a working one or one which they must not call because it will runtime-assert. QEMU's configure test passes (unless you're building with --enable-werror) because the test program using preadv() compiles, but then QEMU crashes at runtime when preadv() is called, with errors like: dyld: lazy symbol binding failed: Symbol not found: _preadv Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication Expected in: /usr/lib/libSystem.B.dylib dyld: Symbol not found: _preadv Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication Expected in: /usr/lib/libSystem.B.dylib Meson's own function availability check has a special case for macOS which adds '-Wl,-no_weak_imports' to the compiler flags, which forces the test to require the real function, not the macOS-version-too-old stub. So this commit fixes the bug where macOS builds on Catalina currently require --disable-werror.

Neither of these lines up nicely with the Clock API, because although both the Clock and the ptimer track the frequency using a representation of whole and fractional nanoseconds, conversion via either period-in-ns or frequency-in-Hz will introduce a rounding error. Add a new function ptimer_set_period_from_clock() which takes the Clock object directly to avoid the rounding issues. This includes a facility for the user to specify that there is a frequency divider between the Clock proper and the timer, as some timer devices like the CMSDK APB dualtimer need this. To avoid having to drag in clock.h from ptimer.h we add the Clock type to typedefs.h.

Most important registers are those related to DRAM initialization and calibration, where SPL initiates process and waits until certain bit is set/cleared. This patch adds these registers, initializes reset values from user's guide and updates state of registers as SPL expects it.

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.
