4 bool "Enable driver model for timer drivers"
7 Enable driver model for timer access. It uses the same API as
8 lib/time.c, but now implemented by the uclass. The first timer
9 will be used. The timer is usually a 32 bits free-running up
10 counter. There may be no real tick, and no timer interrupt.
13 bool "Enable driver model for timer drivers in SPL"
16 Enable support for timer drivers in SPL. These can be used to get
17 a timer value when in SPL, or perhaps for implementing a delay
18 function. This enables the drivers in drivers/timer as part of an
22 bool "Enable driver model for timer drivers in TPL"
25 Enable support for timer drivers in TPL. These can be used to get
26 a timer value when in TPL, or perhaps for implementing a delay
27 function. This enables the drivers in drivers/timer as part of an
31 bool "Enable driver model for timer drivers in VPL"
35 Enable support for timer drivers in VPL. These can be used to get
36 a timer value when in VPL, or perhaps for implementing a delay
37 function. This enables the drivers in drivers/timer as part of an
41 bool "Allow timer to be used early in U-Boot"
43 # initr_bootstage() requires a timer and is called before initr_dm()
44 # so only the early timer is available
47 In some cases the timer must be accessible before driver model is
