2015-02-19cmd_i2c: quit I2C commands immediately on errorMasahiro Yamada1-13/+13

2015-02-17cmd_fdt: Print the control fdt in terms of virtual memoryJoe Hershberger1-1/+1
If you want to inspect the control device tree using the fdt command, the "fdt address -c" command previously unhelpfully printed the phys memory address of the device tree. That address could not then be used to set the fdt address for inspection. Changed the resulting print to one that can be copied directly to the 'fdt address <addr>' command.

2015-02-12Introduce board_init_f_mem() to handle early memory layoutSimon Glass1-0/+18
At present on some architectures we set up the following before calling board_init_f(): - global_data - stack - early malloc memory Adding the code to support early malloc and global data setup to every arch's assembler start-up is a pain. Also this code is not actually architecture-specific. We can use common code for all architectures and with a bit of care we can write this code in C. Add a new function to deal with this. It should be called after memory is available, with a pointer to the top of the area that should be used before relocation. The function will set things up and return the lowest memory address that it allocated/used. That can then be set as the top of the stack. Note that on some archs this function will use the stack, so the stack pointer should be set to same value as is pased to board_init_f_mem(). A margin of 128 bytes will be left for this stack, so that it is not overwritten. This means that 64 bytes is wasted by this early call. This is not strictly necessary on several more modern archs, so we could remove this at the cost of some arch-dependent code. With this function there is no-longer any need for the assembler code to zero global_data or set up the early malloc pointers. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-02-12malloc_simple: Return NULL on malloc failure rather then calling panic()Hans de Goede1-1/+1
All callers of malloc should already do error checking, and may even be able to continue without the alloc succeeding. Moreover, common/malloc_simple.c is the only user of .rodata.str1.1 in common/built-in.o when building the SPL, triggering this gcc bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303 Causing .rodata to grow with e.g. 0xc21 bytes, nullifying all benefits of using malloc_simple in the first place.

2015-02-10lcd: split splash code into its own functionNikita Kiryanov2-30/+38
lcd_logo() currently performs tasks well beyond just displaying the logo. It has code which displays splash image, it has logic which determines when the different display features are displayed, and it is coupled with the lcd console because it holds the responsibility of returning the lcd console base address. Make lcd_logo() just about the logo by: * Moving splash image display code into a dedicated function * Moving the logic regarding when various features are displayed to lcd_clear() (which is arguably not the correct name for housing such code either, but it is currently the most fitting location code wise) * Move the responsibility of setting the console base address to lcd_clear() too.
