2022-07-06board: ti: common: board_detect: Do 1byte address checks first.Nishanth Menon1-10/+10
Do 1 byte address checks first prior to doing 2 byte address checks. When performing 2 byte addressing on 1 byte addressing eeprom, the second byte is taken in as a write operation and ends up erasing the eeprom region we want to preserve. While we could have theoretically handled this by ensuring the write protect of the eeproms are properly managed, this is not true in case where board are updated with 1 byte eeproms to handle supply status. Flipping the checks by checking for 1 byte addressing prior to 2 byte addressing check prevents this problem at the minor cost of additional overhead for boards with 2 byte addressing eeproms.

2022-07-06board: ti: common: Handle the legacy eeprom address width properlyNishanth Menon1-7/+15
Due to supply chain issues, we are starting to see a mixture of eeprom usage including the smaller 7-bit addressing eeproms such as 24c04 used for eeproms. These eeproms don't respond well to 2 byte addressing and fail the read operation. We do have a check to ensure that we are reading the alternate addressing size, however the valid failure prevents us from checking at 1 byte anymore. Rectify the same by falling through and depend on header data comparison to ensure that we have valid data. Signed-off-by: Nishanth Menon <nm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2022-07-06board: ti: common: Optimize boot when detecting consecutive bad recordsNishanth Menon1-1/+4
The eeprom data area is much bigger than the data we intend to store, however, with bad programming, we might end up reading bad records over and over till we run out of eeprom space. instead just exit when 10 consecutive records are read.

2022-06-23linker_lists: Rename sections to remove . prefixAndrew Scull1-2/+2
Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters.

2022-06-16board: ti: am335x: eth_cpsw should depend on CONFIG_NETCorentin LABBE1-1/+1
The origin of this patch is the breaking of am335x-hs boot due to commit e41651fffda7 ("dm: Support parent devices with of-platdata") HS boards have less SRAM for SPL and so this commit increased memory usage beyond am335x limit. This commit added 10 driver binding pass and am335x boot only if one pass is done. SPL try to do more than one pass due to eth_cpsw failing. Since HS SPL does not need network (and NET is already disabled in config), the easiest fix is to "remove" eth_cpsw from SPL by testing if NET is enabled.

Since there are 2 Ethernet ports with 2 modes, there can be 4 configurations but for now we consider both ports in different modes to be an invalid configuration and prevent boot in that case.

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and stemmy, disable ATAG support. A large number of platforms had enabled support but never supported a kernel so old as to require it. Further, some platforms are old enough to support both, but are well supported by devicetree booting, and have been for a number of years. This is because some of the ATAGs related functions have been re-used to provide the same kind of information, but for devicetree or just generally to inform the user. When needed still, rename these functions to get_board_revision() instead, to avoid conflicts. In other cases, these functions were simply unused, so drop them.
