CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

|
|
* TOP5200 differences from IceCube:
|
|
* 1 FLASH Bank for one Chip only, up to 64 MB in 16 MB Banks
|
|
* bank switch controlled by TIMER_6(LSB) and TIMER_7(MSB) Pins
|
|
* 1 SDRAM/DDRAM Bank up to 256 MB
|
|
* local VPD I2C Bus is software driven and uses
|
|
* GPIO_WKUP_6 for SDA, GPIO_WKUP_7 for SCL
|
|
* FLASH is re-located at 0xff000000
|
|
* Internal regs are at 0xf0000000
|
|
* Reset jumps to 0x00000100
