[efi] Centralise definition of efi_cpu_nap()

2024-09-13T13:38:23+00:00

Define a cpu_halt() function which is architecture-specific but platform-independent, and merge the multiple architecture-specific implementations of the EFI cpu_nap() function into a single central efi_cpu_nap() that uses cpu_halt() if applicable. Signed-off-by: Michael Brown

[ioapi] Centralise definitions for dummy PIO

2023-06-29T14:40:24+00:00

There is no common standard for I/O-space access for non-x86 CPU families, and non-MMIO peripherals are vanishingly rare. Generalise the existing ARM definitions for dummy PIO to allow for reuse by other CPU architectures. Signed-off-by: Michael Brown

[ioapi] Move PAGE_SHIFT to bits/io.h

2023-02-06T12:34:21+00:00

The PAGE_SHIFT definition is an architectural property, rather than an aspect of a particular I/O API implementation (of which, in theory, there may be more than one per architecture). Reflect this by moving the definition to the top-level bits/io.h for each architecture. Signed-off-by: Michael Brown

[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
