/*
 * Switches uACPI into tables-subsystem-only mode and strips all other code.
 * This means only the table API will be usable, no other subsystems are
 * compiled in. In this mode, uACPI only depends on the following kernel APIs:
 * - uacpi_kernel_get_rsdp
 * - uacpi_kernel_{map,unmap}
 * - uacpi_kernel_log
 *
 * Use uacpi_setup_early_table_access to initialize, uacpi_state_reset to
 * deinitialize.
 *
 * This mode is primarily designed for these three use-cases:
 * - Bootloader/pre-kernel environments that need to parse ACPI tables, but
 *   don't actually need a fully-featured AML interpreter, and everything else
 *   that a full APCI implementation entails.
 * - A micro-kernel that has the full AML interpreter running in userspace, but
 *   still needs to parse ACPI tables to bootstrap allocators, timers, SMP etc.
 * - A WIP kernel that needs to parse ACPI tables for bootrapping SMP/timers,
 *   ECAM, etc., but doesn't yet have enough subsystems implemented in order
 *   to run a fully-featured AML interpreter.
