[arm] Provide dummy implementations for {in,out}[s]{b,w,l}

2019-07-14T14:31:25+00:00

It is currently not possible to build the all-drivers iPXE binaries for ARM, since there is no implementation for inb(), outb(), etc. There is no common standard for accessing I/O space on ARM platforms, and there are almost no ARM-compatible peripherals that actually require I/O space accesses. Provide dummy implementations that behave as though no device is present (i.e. ignore writes, return all bits high for reads). This is sufficient to allow the all-drivers binaries to link, and should cause drivers to behave as though no I/O space peripherals are present in the system. Signed-off-by: Michael Brown

[time] Allow timer to be selected at runtime

2017-01-26T08:17:37+00:00

Allow the active timer (providing udelay() and currticks()) to be selected at runtime based on probing during the INIT_EARLY stage of initialisation. TICKS_PER_SEC is now a fixed compile-time constant for all builds, and is independent of the underlying clock tick rate. We choose the value 1024 to allow multiplications and divisions on seconds to be converted to bit shifts. TICKS_PER_MS is defined as 1, allowing multiplications and divisions on milliseconds to be omitted entirely. The 2% inaccuracy in this definition is negligible when using the standard BIOS timer (running at around 18.2Hz). TIMER_RDTSC now checks for a constant TSC before claiming to be a usable timer. (This timer can be tested in KVM via the command-line option "-cpu host,+invtsc".) Signed-off-by: Michael Brown
