x86: simplify ljmp to 32-bit code

2019-12-08T11:10:21Z

You can directly specify the label as the operand for ljmp. This commit saves 4-byte code. Signed-off-by: Masahiro Yamada Reviewed-by: Bin Meng Tested-by: Bin Meng [bmeng: fixed the gas warning] Signed-off-by: Bin Meng

x86: use data32 directive instead of macro for operand-size prefix

2019-12-08T11:10:12Z

This file defines 'a32' and 'o32' macros to avoid magic numbers of operand/address-size prefixing. GAS supports 'data32' and 'addr32' for that purpose. Signed-off-by: Masahiro Yamada Reviewed-by: Bin Meng Tested-by: Bin Meng

common: Move board_get_usable_ram_top() out of common.h

Move this function into init.h which seems to be designed for this sort of thing. Also update the header to declare struct global_data so that it can be included without global_data.h being needed. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

common: Move enable/disable_interrupts out of common.h

Move these two functions into the irq_funcs.h header file. Also move interrupt_handler_t as this is used by the irq_install_handler() function. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

common: Move interrupt functions into a new header

2019-12-02T23:25:00Z

These functions do not use driver model but are fairly widely used in U-Boot. But it is not clear that they will use driver model anytime soon, so we don't want to label them as 'legacy'. Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it is widely used in U-Boot already. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

common: Move ARM cache operations out of common.h

2019-12-02T23:24:58Z

These functions are CPU-related and do not use driver model. Move them to cpu_func.h Signed-off-by: Simon Glass Reviewed-by: Daniel Schwierzeck Reviewed-by: Tom Rini

common: Move some cache and MMU functions out of common.h

2019-12-02T23:23:55Z

These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

common: Move checkcpu() out of common.h

This function belongs in cpu_func.h so move it over. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

x86: Quieten TPL's jump_to_image_no_args()

We already a message indicating that U-Boot is about to jump to SPL, so make this one a debug() to reduce code size. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

We don't need to do this and it is done (in more detail) in U-Boot proper. Drop this to save code space. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
