^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) -------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38)   A generic configuration is provided for each machine, and can be used as the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39)   default by::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) 	make spear13xx_defconfig

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) Layout
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) ------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48)   The common files for multiple machine families (SPEAr3xx, SPEAr6xx and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49)   SPEAr13xx) are located in the platform code contained in arch/arm/plat-spear
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50)   with headers in plat/.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52)   Each machine series have a directory with name arch/arm/mach-spear followed by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53)   series name. Like mach-spear3xx, mach-spear6xx and mach-spear13xx.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55)   Common file for machines of spear3xx family is mach-spear3xx/spear3xx.c, for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56)   spear6xx is mach-spear6xx/spear6xx.c and for spear13xx family is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57)   mach-spear13xx/spear13xx.c. mach-spear* also contain soc/machine specific
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58)   files, like spear1310.c, spear1340.c spear300.c, spear310.c, spear320.c and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59)   spear600.c.  mach-spear* doesn't contains board specific files as they fully
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 60)   support Flattened Device Tree.
