commit 3723d0ce50cdbbd826e1e3799924564310c53dc7
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit 235338084d112e50163e8e5a33733e77d3d63520
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h). The 64-bit time support
is added only for LFS support.
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit 9ea61744c37845d8bfb6cad4bba625fd69d0b068
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h). The 64-bit time support
is added only for LFS support.
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit 83f68d065566dc64d9b463c6de19c1cb929b613d
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h). The 64-bit time support
is added only for LFS support.
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit 263982db0c9e15c0d948e3ed715d89ba547a4159
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit 263982db0c9e15c0d948e3ed715d89ba547a4159
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit 0d7f262f13dfb9a41583dbf157db97827ca6eaa2
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit a81c83df579a07af47b3044f79fe7e1ff1c4a484
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit ce62505e0be36e0d0679eecaab13b0b4822c1e38
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.

commit 6260c7c3775d08ab3ca35a32a9ad338191eb6c80
Author: Lukasz Majewski <lukma@denx.de>
Date: Thu Oct 15 09:30:59 2020 +0200
y2038: Use a common definition for stat
Instead of replicate the same definitions from struct_stat_time64.h
on the multiple struct_stat.h, use a common header which is included
when required (struct_stat_time64_helper.h).
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.
