I'm a bit confused: 'do_irq' is defined in several files,
including CPU-specific (arm920t, 720t etc.) and ARM
architecture library ($(U_BOOT)/lib_arm). So if we build for
arm920t-based platform (provided that CONFIG_USE_IRQ is
defined),

So both are mutual exclusive and finally only one will be compiled.
Exactly! Really I didn't spot that subtle difference -- #ifdef, #ifndef.
Thanks for pointing out.

Hello all,
the board I'm porting U-Boot on, has several peripheral devices, which
are, according to datasheet, are based on PrimeCell PLxx blocks (for
example, vector interrupt controller is PL190 based; GPIOs are based
on PL061 block and so on). I understand that PrimeCells are IP cores,
which
, gpio.
I recently sent a patch for RTC pl031.
U too can contribute if u can send patch's for other peripherals.
Regards
Gururaja

Thats because Most of the ARM based boards doesnt use Interrupts. Atleast as
far as i have seen.
IIRC U-boot is a single process bootloader hence Interrupts are not so much
supported.
Is there any interrupt related drivers in U-boot

Hi,
In U-Boot source tree there are number of drivers with
interrupt service routines running (for example,
$(U_BOOT)/drivers/net/bcm570x.c) as well as various
interrupts related macros (some of them not used thought), if
this is what you mean.
Perhaps these definitions are for future ?

At $(U_BOOT)/drivers/net/bcm570x.c files header, it says
* Broadcom BCM570x Ethernet Driver for U-Boot.
* Support 5701, 5702, 5703, and 5704. Single instance driver.
