Subject: [PATCH 01/14] MACH SAMSUNG: Rename the whole mach to add more CPUs in future
Date: Sun, 25 Dec 2011 21:38:24 +0100	[thread overview]
Message-ID: <1324845517-4601-2-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1324845517-4601-1-git-send-email-jbe@pengutronix.de>

The S3Cxxxx family consists of ARMv4, ARMv5 and ARMv6 types of CPU cores. The
S3C24xx sub family is only one of it. To be able to handle all CPUs in one mach
directory, use a more generic name for it.

-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

-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

-@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_S3C24XX_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.
+

+@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.
