[U-Boot] [PATCH 5/7 v4] integrator: make flash writeable on boot
by Linus Walleij 09 Nov '11

09 Nov '11

This reconfigures the EBI (External Bus Interface) on the integrator so that chip select 1, handling the flash memory, is set to writeable. Without this it is not possible for U-Boot to access flash memory and it crashes on startup since CFI won't work properly. Since this is the first time we use the EBI, we create a header file for its registers.

[U-Boot] please i realy need your help
by Bridget kikalya 09 Nov '11

09 Nov '11

My Dearest, Good day to you, I have decided to contact you after much thought considering the fact that we have not meet before, but because of the circumstance oblige me, I decided to contact you due to the urgency of my present situation here in the refugee camp, I am Miss Bridget Kipkalya Kones, 25yrs old female and I from Kenya here in Africa; my father was the former Kenyan road Minister. He and Assistant Minister of Home Affairs Lorna Laboso had been on board the Cessna 210, which was headed to Kericho and crashed in a remote area called Kajong'a, in western Kenya. The plane crashed on Tuesday 10th, June, 2008. After the death of my beloved father my wicked step mother along with my uncles team together and sold everything that my late father had and share the money within themselves. Unfortunately to me I fined my father's briefcase and when I opened it I found a document, which my late father use to deposit the sum of Eight Million Five Hundred Thousand United State Dollars ($8.500.000.00) in International Micro De Finance Bank, here in Burkina Faso West Africa with my name as next of skin, right now I am in Ouagadougou Capital of Burkina Faso to withdraw the money so that i can start a better life and also further my education. But on my arrival to the Bank, the Bank foreign Operation Department Director whom I meet in person told me that my father instruction to their bank is that the fund would only be release to me when I am married or present a trustee/partner who will help me and invest the fund overseas after the transfer, and the bank ask me to go and look for a foreign partner, that was why I decided to contact you, which I believe that you are going to be honest and reliable person that will help me and stand as my trustee/partner, so that I can present you to the Bank for the release and transfer of the inheritance fund into your bank account in your country, and It is my intention to compensate you with 40% of the total fund for your services and help and the balance shall be my capital in your establishment. As soon as I receive your positive response showing your interest i will put things into action, in the light of the above, I shall appreciate an urgent message indicating your ability and willingness to handle this transaction, awaiting your urgent and positive response, Please do keep this only to your self, i beg you not to disclose it to any body till i come over because am afraid of my wicked stepmother, i will send you my picture in my next email, with due respect, i am pleading that you help me, i am giving all this detailed information with every transparency believing that you will have a clear picture of the base of help i need from you. I hope to hear from you soon, May truth and love be the guiding word in my refuge, Best regard, Yours Sincerely Bridget kipkalya kones

Commit dc8bbea removed a local variable that is used in most ARM boards.
