Subject: Registering RTC access methods in platform_init()

Hello

I have a question regarding the registering of the RTC access methods in
platform_init() in ppc4xx_setup.c.
The problem is quite similar to the one i stated in
one of my previous e-mails "Additional IRQ handlers in ppc4xx_init_IRQ()".

Currently this is done in this way:

#ifdef CONFIG_PPC_RTC
/* new timer stuff */
	ppc_md.time_init = todc_time_init;
	ppc_md.set_rtc_time = todc_set_rtc_time;
	ppc_md.get_rtc_time = todc_get_rtc_time;

#if !defined(CONFIG_PIP405) && !defined(CONFIG_MIP405)
	ppc_md.nvram_read_val = todc_direct_read_val;
	ppc_md.nvram_write_val = todc_direct_write_val;
#else
	ppc_md.nvram_read_val = todc_mc146818_read_val;
	ppc_md.nvram_write_val = todc_mc146818_write_val;
#endif
#endif

All other ports using a MC146818 RTC have their own xxx_setup.c file
(Sandpoint, Adirondack, ...).

I suppose the preferred way to solve this is to replace this whole init
code by a call to a board specific init routine?
