As a general rule, it -should not be referenced outside of arch/arm/kernel/setup.c:setup_arch(). - -There are a lot of parameters listed in there, and they are described -below: - - page_size - - This parameter must be set to the page size of the machine, and - will be checked by the kernel. - - nr_pages - - This is the total number of pages of memory in the system. If - the memory is banked, then this should contain the total number - of pages in the system. - - If the system contains separate VRAM, this value should not - include this information. - - ramdisk_size - - This is now obsolete, and should not be used. - - flags - - Various kernel flags, including: - bit 0 - 1 = mount root read only - bit 1 - unused - bit 2 - 0 = load ramdisk - bit 3 - 0 = prompt for ramdisk - - rootdev - - major/minor number pair of device to mount as the root filesystem. - - video_num_cols - video_num_rows - - These two together describe the character size of the dummy console, - or VGA console character size. They should not be used for any other - purpose. - - It's generally a good idea to set these to be either standard VGA, or - the equivalent character size of your fbcon display. This then allows - all the bootup messages to be displayed correctly. - - video_x - video_y - - This describes the character position of cursor on VGA console, and - is otherwise unused. (should not be used for other console types, and - should not be used for other purposes). - - memc_control_reg - - MEMC chip control register for Acorn Archimedes and Acorn A5000 - based machines. May be used differently by different architectures. - - sounddefault - - Default sound setting on Acorn machines. May be used differently by - different architectures. - - adfsdrives - - Number of ADFS/MFM disks. May be used differently by different - architectures. - - bytes_per_char_h - bytes_per_char_v - - These are now obsolete, and should not be used. - - pages_in_bank[4] - - Number of pages in each bank of the systems memory (used for RiscPC). - This is intended to be used on systems where the physical memory - is non-contiguous from the processors point of view. - - pages_in_vram - - Number of pages in VRAM (used on Acorn RiscPC). This value may also - be used by loaders if the size of the video RAM can't be obtained - from the hardware. - - initrd_start - initrd_size - - This describes the kernel virtual start address and size of the - initial ramdisk. - - rd_start - - Start address in sectors of the ramdisk image on a floppy disk. - - system_rev - - system revision number. - - system_serial_low - system_serial_high - - system 64-bit serial number - - mem_fclk_21285 - - The speed of the external oscillator to the 21285 (footbridge), - which control's the speed of the memory bus, timer & serial port. - Depending upon the speed of the cpu its value can be between - 0-66 MHz. If no params are passed or a value of zero is passed, - then a value of 50 Mhz is the default on 21285 architectures. - - paths[8][128] - - These are now obsolete, and should not be used. - - commandline - - Kernel command line parameters. Details can be found elsewhere. |
