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
50 use an early timer. These functions must be supported by your timer
54 bool "Altera timer support"
57 Select this to enable a timer for Altera devices. Please find
65 associated with timer tick.
68 bool "ARC timer support"
77 bool "ARM timer watchdog (TWD) timer support"
80 Select this to enable support for the ARM global timer watchdog timer.
83 bool "Aspeed ast2400/ast2500 timer support"
87 Select this to enable timer for Aspeed ast2400/ast2500 devices.
88 This is a simple sys timer driver, it is compatible with lib/time.c,

174 This timer is present on Renesas RZ/A1 R7S72100 SoCs.
177 int "x86 TSC timer frequency in Hz"
182 early timer and the frequency can neither be calibrated via some
193 At the moment, only the first timer is used by the driver.
196 bool "Nuvoton NPCM timer support"
199 Select this to enable a timer on Nuvoton NPCM SoCs.
200 NPCM timer module has 5 down-counting timers, only the first timer
201 is used to implement timer ops. No support for early timer and
202 boot timer.
205 bool "Omap timer support"
208 Select this to enable an timer for Omap devices.
211 bool "Orion timer support"
216 Select this to enable an timer for Orion and Armada devices
220 bool "RISC-V timer support"
223 Select this to enable support for a generic RISC-V S-Mode timer

263 bool "Tegra timer support"
267 Select this to enable support for the timer found on
271 bool "x86 Time-Stamp Counter (TSC) timer support"
274 Select this to enable Time-Stamp Counter (TSC) timer for x86.
277 bool "Read the TSC timer base on start-up"
280 On x86 platforms the TSC timer tick starts at the value 0 on reset.
281 This it makes no sense to read the timer on boot and use that as the
