-Native Execution of U-Boot
-==========================
-
-The 'sandbox' architecture is designed to allow U-Boot to run under Linux on
-almost any hardware. To achieve this it builds U-Boot (so far as possible)
-as a normal C application with a main() and normal C libraries.
-
-All of U-Boot's architecture-specific code therefore cannot be built as part
-of the sandbox U-Boot. The purpose of running U-Boot under Linux is to test
-all the generic code, not specific to any one architecture. The idea is to
-create unit tests which we can run to test this upper level code.
-
-CONFIG_SANDBOX is defined when building a native board.
-
-The chosen vendor and board names are also 'sandbox', so there is a single
-board in board/sandbox/sandbox.
-
-CONFIG_SANDBOX_BIG_ENDIAN should be defined when running on big-endian
-machines.
-
-Note that standalone/API support is not available at present.
-
-The serial driver is a very simple implementation which reads and writes to
-the console. It does not set the terminal into raw mode, so cursor keys and
-history will not work yet.
-
-
-SPI Emulation
--------------
-
-Sandbox supports SPI and SPI flash emulation.
-
-This is controlled by the spi_sf argument, the format of which is:
-
- bus:cs:device:file
-
- bus - SPI bus number
- cs - SPI chip select number
- device - SPI device emulation name
- file - File on disk containing the data
-
-For example:
-
- dd if=/dev/zero of=spi.bin bs=1M count=4
- ./u-boot --spi_sf 0:0:M25P16:spi.bin
-
-With this setup you can issue SPI flash commands as normal:
-
-=>sf probe
-SF: Detected M25P16 with page size 64 KiB, total 2 MiB
-=>sf read 0 0 10000
-SF: 65536 bytes @ 0x0 Read: OK
-=>
-
-Since this is a full SPI emulation (rather than just flash), you can
-also use low-level SPI commands:
-
-=>sspi 0:0 32 9f
-FF202015
-
-This is issuing a READ_ID command and getting back 20 (ST Micro) part
-0x2015 (the M25P16).
-
-Drivers are connected to a particular bus/cs using sandbox's state
-structure (see the 'spi' member). A set of operations must be provided
-for each driver.
-
-
-Configuration settings for the curious are:
-
-CONFIG_SANDBOX_SPI_MAX_BUS
- The maximum number of SPI buses supported by the driver (default 1).
-
-CONFIG_SANDBOX_SPI_MAX_CS
- The maximum number of chip selects supported by the driver
- (default 10).
-
-CONFIG_SPI_IDLE_VAL
- The idle value on the SPI bus
-
-
-Tests
------
-
-So far we have no tests, but when we do these will be documented here.
