u-boot.git/arch/x86/cpu/cpu.c, branch v2016.01 Unnamed repository; edit this file 'description' to name the repository. x86: Move i8254_init() to x86_cpu_init_f() 2015-12-09T09:44:44+00:00 Bin Meng bmeng.cn@gmail.com 2015-12-09T01:31:39+00:00 4932443d260d23c882e48eefcc66a83dfca7ee5a Right now i8254_init() is called from timer_init() in the tsc timer driver. But actually i8254 and tsc are completely different things. Since tsc timer has been converted to driver model, we should find a new place that is appropriate for U-Boot to call i8254_init(), which is now x86_cpu_init_f().

x86: Switch to using generic global_data setup 2015-08-14T15:50:10+00:00 Simon Glass sjg@chromium.org 2015-08-11T02:44:32+00:00 f0c7d9c74642ccd6c76993b721b0fb87aab685fa There is quite a bit of assembler code that can be removed if we use the generic global_data setup. Less arch-specific code makes it easier to add new features and maintain the start-up code. Drop the unneeded code and adjust the hooks in board_f.c to cope.
