10 select ARCH_EARLY_INIT_R
16 bool "Add a Remote Management Unit (RMU) binary"
18 Select this option to add a Remote Management Unit (RMU) binary
19 to the resulting U-Boot image. It is a data block (up to 64K) of
20 machine-specific code which must be put in the flash for the RMU
21 within the Quark SoC processor to access when powered up before
22 system BIOS is executed.
25 string "Remote Management Unit (RMU) binary filename"
29 The filename of the file to use as Remote Management Unit (RMU)
30 binary in the board directory.
33 hex "Remote Management Unit (RMU) binary location"
37 The location of the RMU binary is determined by a strap. It must be
38 put in flash at a location matching the strap-determined base address.
40 The default base address of 0xfff00000 indicates that the binary must
41 be located at offset 0 from the beginning of a 1MB flash device.
61 Embedded SRAM (eSRAM) memory-mapped base address.
71 Root Complex register block memory-mapped base address.
77 ACPI Power Managment 1 (PM1) i/o-mapped base address.
78 This device is defined in ACPI specification, with 16 bytes in size.
84 ACPI Processor Block (PBLK) i/o-mapped base address.
85 This device is defined in ACPI specification, with 16 bytes in size.
91 SPI DMA i/o-mapped base address.
97 GPIO i/o-mapped base address.
103 ACPI General Purpose Event 0 (GPE0) i/o-mapped base address.
104 This device is defined in ACPI specification, with 64 bytes in size.
110 Watchdog timer i/o-mapped base address.
120 Space in bytes in eSRAM used as Cache-As-ARM (CAR).
121 Note this size must not exceed eSRAM's total size.
