[U-Boot] [PATCH v2] davinci: Rewrite timer.c to use tbl/tbu emulation variables in gd
by Nick Thompson 09 Dec '10

09 Dec '10

This change allows the davinci timer functions to be used before relocation since it avoids using static variables prior to BSS being made available. The code is based on that used in the at91 timers, modified to use a davinci specific hardware timer. It also maintains reset_timer() to allow deprecated timer usage to continue to work (for example, in nand_base.c) Signed-off-by: Nick Thompson <nick.thompson(a)ge.com> --- This patch relies on http://patchwork.ozlabs.org/patch/73758/ which has been applied to the ARM tree.

[U-Boot] [PATCH 1/2 ] [NEXT] Remove redundant config.mk files
by Wolfgang Denk 09 Dec '10

09 Dec '10

Recent cleanup actions resulted in a number of config.mk files that contained only redundant entries like PLATFORM_CPPFLAGS += -I$(TOPDIR) or settings of variables that were not used anywhere in the code, like TEXT_END = 0xfe080000 Remove these unnecessary files.

[U-Boot] [PATCH] ARM: make timer variables in gt_t available for all ARM platforms

[U-Boot] [PATCH] hwconfig: Fix handling of env_hwconfig, board_hwconfig, and cpu_hwconfig
by Kumar Gala 08 Dec '10

08 Dec '10

The handling of env_hwconfig, board_hwconfig, and cpu_hwconfig got broken when we removed the boards defining dummy board_hwconfig & cpu_hwconfig values. We fix this by handling the various strings in priority order. If hwconfig_parse returns NULL for a given string we check the next one in order (env_hwconfig, board_hwconfig, followed by cpu_hwconfig).

[U-Boot] Installing UBoot on X86 architecture with BIOS
by nima chavooshi 08 Dec '10

08 Dec '10

Hi I am newbie on Uboot or other boot loaders context.we intend to install our Linux based OS on Portwell (is not Embedded ) appliances and want to choose one boot loader with some features.Of course our appliances have BIOS. before any argue, one question arises: Is it possible to install Uboot on system that has BIOS? if so, Is it reasonable ? Some features we have need : 1- show detail information about hardware before loading kernel,such as storage system,ram capacity,CPU family and so on. 2- boot over net. 3-load kernel from storage. I have had some search on LILO, but before any decision, I want to make sure about other boot loaders. Thanks for any help or guidance -- N.Chavoshi
