Introduce generic link section.h symbol files

2013-03-15T20:13:58Z

We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini (version 5) Signed-off-by: Simon Glass

sandbox: Add un/map_sysmen() to deal with sandbox's ram_buf

2013-03-01T03:09:22Z

Sandbox doesn't actually provide U-Boot access to the machine's physical memory. Instead it provides a RAM buffer of configurable size, and all memory accesses are within that buffer. Sandbox memory starts at 0 and is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer might produce unpredictable results in the event of an error, and would expose the host machine's memory architecture to the sandbox U-Boot. Most U-Boot functions assume that they can just access memory at given address. For sandbox this is not true. Add a map_sysmem() call which converts a U-Boot address to a system address. In most cases this is a NOP, but for sandbox it returns a pointer to that memory inside the RAM buffer. To get a U-Boot feature to work correctly within sandbox, you should call map_sysmem() to get a pointer to the address, and then use that address for any U-Boot memory accesses.

Add architecture-specific global data

2013-02-01T20:07:49Z

We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain. Signed-off-by: Simon Glass

sandbox: Change global data baudrate to int

2012-10-19T22:25:46Z

This doesn't need to be a long, so change it. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

sandbox: Add asm/errno.h

2012-09-29T17:00:29Z

This file is required for all archs. Fixes a sandbox build break on ext4. Signed-off-by: Simon Glass

global_data: unify global flag defines

2012-08-09T19:46:32Z

All the global flag defines are the same across all arches. So unify them in one place, and add a simple way for arches to extend for their needs. Signed-off-by: Mike Frysinger

net: punt bd->bi_ip_addr

2012-05-15T22:32:05Z

This field gets read in one place (by "bdinfo"), and we can replace that with getenv("ipaddr"). After all, the bi_ip_addr field is kept up-to-date implicitly with the value of the ipaddr env var. Signed-off-by: Mike Frysinger Reviewed-by: Joe Hershberger

sandbox: add getopt support

2012-03-12T15:06:01Z

This adds simple command-line parsing to sandbox. The idea is that it sets up the state with options provided, and this state can then be queried later, as needed. New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro, pointers are automatically gathered up in a special section, and then the core code takes care of gathering them up and processing at runtime. This way there is no central place where we have to store a list of flags with ifdefs. Signed-off-by: Simon Glass Signed-off-by: Mike Frysinger
