-@page dev_s3c24xx_nandboot_handling Booting from NAND
-
-To be able to boot from NAND memory only, enable the S3C24x0 NAND driver. Also
-enable CONFIG_S3C24XX_NAND_BOOT and CONFIG_MACH_HAS_LOWLEVEL_INIT to be
-able to call the s3c24x0_nand_boot() assembler routine from within the
-machine specific board_init_lowlevel() assembler function.
-
-@note This routine assumes an already working SDRAM controller and
-an initialized stack pointer.
-
-@note Basicly this routine runs from inside the internal SRAM. After load of
-the whole barebox image from the NAND flash memory into the SDRAM it adjusts
-the link register to the final SDRAM adress and returns.
-
-@note In the NAND boot mode, ECC is not checked. So, the first x KBytes used
-by barebox should have no bit error.
-
-Due to the fact the code to load the whole barebox from NAND must fit into
-the first 4kiB of the barebox image, the shrinked NAND driver is very
-minimalistic. Setup the NAND access timing is done in a safe manner, what
-means: Slowest possible values are used. If you want to increase the speed you
-should define the BOARD_DEFAULT_NAND_TIMING to a valid setting into the
-NFCONF register and add it to your board specific config.h. Refer S3C24x0's
-datasheet for further details. The macro #CALC_NFCONF_TIMING could help to
-calculate the register setting in a hardware independent manner.
-
-@note The regular NAND driver uses a platform data structure to define the
-NAND access timings.
-
-@note Its still possible to boot this image from NOR memory. If this routine
-detects it is running from NOR instead of the internal SRAM it skips any
-loading and returns immediately.

+@page dev_s3c24xx_pll_handling PLL clock handling
+
+To control the speed of your machine the PLLs must be reconfigured after reset.
+
+For example the S3C2410 CPU wakes up after reset at 120MHz main PLL speed,
+shared with all other system on chip components. Most of the time this
+configuration is to slow for the CPU and to fast for the other components.
+
+PLL reprogramming can be done in the machine specific manner very early when
+the CONFIG_S3C_PLL_INIT and CONFIG_MACH_HAS_LOWLEVEL_INIT symbols are
+defined. The board must provide a board_init_lowlevel() assembler function in
+this case and calling the s3c24x0_pll_init() assembler function.
+
+If the s3c24x0_pll_init() is called a few further symbols must be defined to
+setup the correct values for the machine.
+
+Define in the machine specific config.h the following symbols:
+
+- S3C24XX_CLOCK_REFERENCE with the frequency in Hz of your reference crystal.
+- BOARD_SPECIFIC_CLKDIVN with the value for the main clock ratio register (CLKDIVN)
+- BOARD_SPECIFIC_MPLL with the value for the main PLL setup register
+- BOARD_SPECIFIC_UPLL with the value for the USB PLL setup register
+
+@note Valid values for the PLL settings can be found in the CPU manual.

+enable CONFIG_S3C_NAND_BOOT and CONFIG_MACH_HAS_LOWLEVEL_INIT to be
+able to call the s3c24x0_nand_boot() assembler routine from within the
+machine specific board_init_lowlevel() assembler function.
+
+@note This routine assumes an already working SDRAM controller and
+an initialized stack pointer.
+
+@note Basicly this routine runs from inside the internal SRAM. After load of
+the whole barebox image from the NAND flash memory into the SDRAM it adjusts
+the link register to the final SDRAM adress and returns.
+
+@note In the NAND boot mode, ECC is not checked. So, the first x KBytes used
+by barebox should have no bit error.
+
+Due to the fact the code to load the whole barebox from NAND must fit into
+the first 4kiB of the barebox image, the shrinked NAND driver is very
+minimalistic. Setup the NAND access timing is done in a safe manner, what
+means: Slowest possible values are used. If you want to increase the speed you
+should define the BOARD_DEFAULT_NAND_TIMING to a valid setting into the
+NFCONF register and add it to your board specific config.h. Refer S3C24x0's
+datasheet for further details. The macro #CALC_NFCONF_TIMING could help to
+calculate the register setting in a hardware independent manner.
+
+@note The regular NAND driver uses a platform data structure to define the
+NAND access timings.
+
+@note Its still possible to boot this image from NOR memory. If this routine
+detects it is running from NOR instead of the internal SRAM it skips any
+loading and returns immediately.
