u-boot.git/cpu/blackfin, branch v2009.01 Unnamed repository; edit this file 'description' to name the repository. i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functions 2008-12-15T22:46:21+00:00 Timur Tabi timur@freescale.com 2008-12-03T17:28:30+00:00 ecf5f077c8e77454f532eaac3e3afb7cfc48c62d All implementations of the functions i2c_reg_read() and i2c_reg_write() are identical. We can save space and simplify the code by converting these functions into inlines and putting them in i2c.h.

Blackfin: fix up UART status bit handling 2008-10-23T09:03:51+00:00 Mike Frysinger vapier@gentoo.org 2008-04-09T06:02:07+00:00 f177f4250c729727b1629fa8d8d6556c999e9b8c Some Blackfin UARTs are read-to-clear while others are write-to-clear. This can cause problems when we poll the LSR and then later try and handle any errors detected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Blackfin: small cpu init optimization while setting interrupt mask 2008-10-23T09:03:51+00:00 Mike Frysinger vapier@gentoo.org 2008-10-12T01:19:39+00:00 bd33e5c613cf70e3cb51a73fdd653fe83b942bb0 Use the sti instruction to set the initial interrupt mask rather than banging on the core IMASK MMR to save both space and time.

Blackfin: make baud calculation more accurate 2008-10-23T09:03:51+00:00 Mike Frysinger vapier@gentoo.org 2008-04-20T07:11:53+00:00 25cd33d82ea521b7bd90ca858f8919fae1e9732b We should use the algorithm in the Linux kernel so that the UART divisor calculation is more accurate. It also fixes problems on some picky UARTs that have sampling anomalies. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
