[U-Boot] [Question] Any plan to refactor Generic Board Framework?

[Masahiro Yamada]

Hi.



The generic board code looks really dirty to me:
common/board_f.c is sprinkled with ARCH/CPU/BOARD configs

For example,


#if defined(CONFIG_405GP) || defined(CONFIG_405EP) || \
		defined(CONFIG_440EP) || defined(CONFIG_440GR) || \
		defined(CONFIG_440EPX) || defined(CONFIG_440GRX)
	bd->bi_pci_busfreq = get_PCI_freq();
	bd->bi_opbfreq = get_OPB_freq();
#elif defined(CONFIG_XILINX_405)
	bd->bi_pci_busfreq = get_PCI_freq();
#endif

or

#if defined(CONFIG_8xx) || defined(CONFIG_MPC8260) || defined(CONFIG_5xx) || \
		defined(CONFIG_E500) || defined(CONFIG_MPC86xx)
	bd->bi_immr_base = CONFIG_SYS_IMMR;	/* base  of IMMR register     */
#endif
#if defined(CONFIG_MPC5xxx)
	bd->bi_mbar_base = CONFIG_SYS_MBAR;	/* base of internal registers */
#endif
#if defined(CONFIG_MPC83xx)
	bd->bi_immrbar = CONFIG_SYS_IMMR;
#endif



Is there any plan to fix them? When? By whom?

(They include some old platform macros such as CONFIG_8xx.
Is it worth refactoring? If so, who will do it? )



Besides, there are many 'TODO' marks.
But it seems nothing has happened so far...


Now generic board is suppored in ARM, PPC, MIPS, Sandbox, ARC, x86.

Accoding to doc/README.generic-board,
we are expecting the other architectures will support it before October.
I think we should start to do something now.

If we keep going without any clean-up, I guess it will be messed up.
