* include/configs: drop default definitions of CONFIG_SYS_PBSIZEThomas Petazzoni2017-09-03220-433/+1

* include/config_fallbacks.h: change fallback for CONFIG_SYS_PBSIZEThomas Petazzoni2017-09-031-1/+1
| | | | | | | | | | | | Most of the platforms are using CONFIG_SYS_CBSIZE + sizeof(CONFIG_SYS_PROMPT) + 16 as their value for CONFIG_SYS_PBSIZE, so let's adopt this for the fallback value of CONFIG_SYS_PBSIZE. This will allow us to drop an explicit definition of CONFIG_SYS_PBSIZE from a large number of platforms.

* include/config_fallbacks.h: add default for CONFIG_SYS_CBSIZEThomas Petazzoni2017-09-031-0/+9
| | | | | | | | | | | | | | | | | CONFIG_SYS_CBSIZE contains the buffer size for input for the console. The vast majority of platforms define them to some reasonable value (256, 512 or 1024 bytes), and it is quite annoying to repeat this definition for all platforms while it isn't really HW-related. Therefore, let's provide a sane fallback value in config_fallbacks.h, so that platforms can rely on it instead of having to explicitly define it. We use 1024 when KGDB is enabled, and 256 otherwise, which is what the majority of the platforms are doing.

* part: efi: Disable overlap checkMaxime Ripard2017-09-031-7/+21
| | | | | | | | | | | | | | | | | | | | The current code checks that no partitions overlap with the GPT partition table using the offset of the first LBA usable for that partition. This works fine, unless you have a partition entry that is further away than it usually is and you want to create partitions in the gap between the GPT header and the GPT partition entries, for example to reflash a bootloader that needs to be set there. Rework the test to something a bit smarter that checks whether a partition would overlap with either the GPT header or the partition entries, no matter where it is on the disk. Partitions that do not have a start LBA specified will still start at the first LBA usable set in the GPT header, to avoid weird behaviours.

This has two exceptions, first am335x_evm needs to be converted to DM in SPL and then it can stop undef'ing CONFIG_DM_USB. Leaving this as-is results in a build failure, and without work, run time failure. The other case is am43xx_evm.h and in turn am43xx_evm_usbhost_boot.
