* x86: Introduce INTEL_MID quirk optionAndy Shevchenko2017-02-21-0/+14
| | | | | | | | | | | | | | | | | | Intel Mobile Internet Device (MID) platforms have special treatment in some cases, such as CPU enumeration or boot parameters configuration. Besides that several drivers are specifically developed for the IP blocks found on Intel MID platforms. Those drivers will be dependent to this option. Here we introduce specific quirk option for such cases. It is supposed to be selected by Intel MID platform boards, for example, Intel Edison.

* x86: Force 32-bit jumps in interrupt handlersJ. Tang2017-02-21-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending upon the compiler used, IRQ entries could vary in sizes. With GCC 5.x, the code generator will use short jumps for some IRQ entries but near jumps for others. For example, GCC 5.4.0 generates the following: $ objdump -d interrupt.o <snip> 00000207 <irq_18>: 207: 6a 12 push $0x12 209: eb 85 jmp 190 <irq_common_entry> 0000020b <irq_19>: 20b: 6a 13 push $0x13 20d: eb 81 jmp 190 <irq_common_entry> 0000020f <irq_20>: 20f: 6a 14 push $0x14 211: e9 7a ff ff ff jmp 190 <irq_common_entry> 00000216 <irq_21>: 216: 6a 15 push $0x15 218: e9 73 ff ff ff jmp 190 <irq_common_entry> This causes a problem in cpu_init_interrupts(), because the IDT setup assumed same sizes for all IRQ entries. GCC 4.x always generated 32-bit jumps, so this previously was not a problem. The fix is to force 32-bit near jumps for all entries within the inline assembly. This works for GCC 5.x, and 4.x was already using that form of jumping. Signed-off-by: Jason Tang <tang@jtang.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

| | | | | | | | | | | | | | | | | | At present all 16/32-bit init is controlled by CONFIG_X86_RESET_VECTOR. If this is enabled, then U-Boot is the 'first' boot loader and handles execution from the reset vector through to U-Boot's command prompt. If it is not enabled then U-Boot starts at the 32-bit entry and skips most of its init, assuming that the previous boot loader has done this already. With the move to suport 64-bit operation, we have more cases to consider. The 16-bit and 32-bit init may be in SPL rather than in U-Boot proper. Add Kconfig options which control the location of the 16-bit and the 32-bit init. These are not intended to be user-setting except for experimentation. Their values should be determined by whether 64-bit U-Boot is used. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
