45 menu "Memory configuration"
48 hex "Physical memory start address"
49 default "0x50000000" if MACH_G3EVM
50 default "0x40000000" if MACH_G4EVM
51 default "0x40000000" if MACH_AP4EVB
54 Tweak this only when porting to a new machine which does not
55 already have a defconfig. Changing it from the known correct
56 value on any of the known systems will only lead to disaster.
59 hex "Physical memory size"
60 default "0x08000000" if MACH_G3EVM
61 default "0x08000000" if MACH_G4EVM
62 default "0x10000000" if MACH_AP4EVB
65 This sets the default memory size assumed by your kernel. It can
66 be overridden as normal by the 'mem=' argument on the kernel command
71 menu "Timer and clock configuration"
73 config SHMOBILE_TIMER_HZ
74 int "Kernel HZ (jiffies per second)"
78 Allows the configuration of the timer frequency. It is customary
79 to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
80 case of low timer frequencies other values may be more suitable.
81 SH-Mobile systems using a 32768 Hz RCLK for clock events may want
82 to select a HZ value such as 128 that can evenly divide RCLK.
83 A HZ value that does not divide evenly may cause timer drift.
86 bool "CMT timer driver"
89 This enables build of the CMT timer driver.
