[U-Boot] [PATCH v2 04/17] buildman: Convert to Python 3

Simon Glass sjg at chromium.org
Thu Oct 31 13:42:53 UTC 2019


Convert buildman to Python 3 and make it use that, to meet the 2020
deadline.

Signed-off-by: Simon Glass <sjg at chromium.org>
---

Changes in v2:
- Use integer division for multiprocessing.cpu_count()
- Use integer division in SetupBuild() and GetActionSummary()
- Use HTTPMessage.getheader() instead of HTTPMessage.get()
- Use integer division in toolchain.Download()
- Use explicit utf-8 encoding in Boards.ReadBoards()
