the "64" category of the Power ISA). This is necessary for ePAPR
compliance, among other possible reasons.
- CONFIG_SYS_FSL_TBCLK_DIV
-
- Defines the core time base clock divider ratio compared to the
- system clock. On most PQ3 devices this is 8, on newer QorIQ
- devices it can be 16 or 32. The ratio varies from SoC to Soc.
-
CONFIG_SYS_FSL_ERRATUM_A004510
Enables a workaround for erratum A004510. If set,
the defaults discussed just above.
- Cache Configuration for ARM:
- CONFIG_SYS_L2_PL310 - Enable support for ARM PL310 L2 cache
- controller
CONFIG_SYS_PL310_BASE - Physical base address of PL310
controller register space
CONFIG_LAN91C96_USE_32_BIT
Define this to enable 32 bit addressing
- CONFIG_SMC91111
- Support for SMSC's LAN91C111 chip
-
- CONFIG_SMC91111_BASE
- Define this to hold the physical address
- of the device (I/O space)
-
- CONFIG_SMC_USE_32_BIT
- Define this if data bus is 32 bits
-
- CONFIG_SMC_USE_IOFUNCS
- Define this to use i/o functions instead of macros
- (some hardware wont work with macros)
-
CONFIG_SYS_DAVINCI_EMAC_PHY_COUNT
Define this if you have more then 3 PHYs.
- Keyboard Support:
See Kconfig help for available keyboard drivers.
-- LCD Support: CONFIG_LCD
-
- Define this to enable LCD support (for output to LCD
- display); also select one of the supported displays
- by defining one of these:
-
- CONFIG_NEC_NL6448AC33:
-
- NEC NL6448AC33-18. Active, color, single scan.
-
- CONFIG_NEC_NL6448BC20
-
- NEC NL6448BC20-08. 6.5", 640x480.
- Active, color, single scan.
-
- CONFIG_NEC_NL6448BC33_54
-
- NEC NL6448BC33-54. 10.4", 640x480.
- Active, color, single scan.
-
- CONFIG_SHARP_16x9
-
- Sharp 320x240. Active, color, single scan.
- It isn't 16x9, and I am not sure what it is.
-
- CONFIG_SHARP_LQ64D341
-
- Sharp LQ64D341 display, 640x480.
- Active, color, single scan.
-
- CONFIG_HLD1045
-
- HLD1045 display, 640x480.
- Active, color, single scan.
-
- CONFIG_OPTREX_BW
-
- Optrex CBL50840-2 NF-FW 99 22 M5
- or
- Hitachi LMG6912RPFC-00T
- or
- Hitachi SP14Q002
-
- 320x240. Black & white.
-
- CONFIG_LCD_ALIGNMENT
-
- Normally the LCD is page-aligned (typically 4KB). If this is
- defined then the LCD will be aligned to this value instead.
- For ARM it is sometimes useful to use MMU_SECTION_SIZE
- here, since it is cheaper to change data cache settings on
- a per-section basis.
-
-
- CONFIG_LCD_ROTATION
-
- Sometimes, for example if the display is mounted in portrait
- mode or even if it's mounted landscape but rotated by 180degree,
- we need to rotate our content of the display relative to the
- framebuffer, so that user can read the messages which are
- printed out.
- Once CONFIG_LCD_ROTATION is defined, the lcd_console will be
- initialized with a given rotation from "vl_rot" out of
- "vidinfo_t" which is provided by the board specific code.
- The value for vl_rot is coded as following (matching to
- fbcon=rotate:<n> linux-kernel commandline):
- 0 = no rotation respectively 0 degree
- 1 = 90 degree rotation
- 2 = 180 degree rotation
- 3 = 270 degree rotation
-
- If CONFIG_LCD_ROTATION is not defined, the console will be
- initialized with 0degree rotation.
-
- MII/PHY support:
CONFIG_PHY_CLOCK_FREQ (ppc4xx)
